Episodes

  1. 42.From Losing Baby Teeth to New Teeth

    When children begin losing their baby teeth, parents often find themselves with a whole new set of questions. Why has one child already started losing teeth while another has not? How long should it take for a permanent tooth to appear? Why do the two sides of the mouth seem to change at…

  2. 41.How Children Learn to Find Their Own Next Step — Developing Autonomy

    Your child has a room full of toys—so why do they still come over and ask: “What should I do now?” This does not necessarily mean they do not know how to play, lack imagination, or are not independent enough. When no one provides the next step, children have to do something surprisingly complex:...

  3. 40.They Can Do It—Why Do They Still Need Reminders? | Self-Regulation

    Your child knows how to get dressed, clean up, and prepare to leave the house—so why do they still need so many reminders? It is easy to assume that once a child can complete a task, they already know how to manage it independently. But if we slow the process down, we may notice something...

  4. 39.They Remembered—So Why Did They Forget? — The Development of Prospective Memory

    When children sincerely agree to do something later, why does it sometimes seem to vanish from their minds when the moment actually arrives? And why can a simple reminder suddenly bring it all back? At the heart of this puzzle is prospective memory—our ability to remember to carry out an…

  5. 38.Beyond Following Directions: How Children Begin to Plan Ahead

    If a five-year-old can follow directions—put on their shoes, grab a water bottle, brush their teeth, and get ready for bed—does that mean they already know how to plan? Not quite. Following a plan and creating one are two very different things. For young children, planning doesn’t begin with...

  6. 37."Fiver more minutes": why is it so hard for children to stop?

    Why do preschoolers keep asking for “five more minutes”—even when we have already warned them that it is time to stop? For young children, leaving the playground, putting away the blocks, ending a favorite activity, or settling down for bed is not simply a matter of listening or refusing to…

    more
  7. 36.Beyond Hurry: Helping Children Build a Sense of Time

    Why do preschool children seem to slow down exactly when it is time to leave the house? And why does saying “hurry up” often make the morning feel even harder? In this episode of The Scientific Parenting Diary, we explore how young children develop a sense of time, why clock-based phrases like...

  8. 35.From Preschool to Kindergarten: What Should Parents Prepare?

    Around age five or six, many children move from preschool, daycare, or early childhood programs into a more formal school setting such as Kindergarten. To adults, this may look like simply changing schools. But for children, it can mean a major shift in daily rhythm, teachers, classmates, rules,...

  9. 34.Helping Kids Find Day and Night Again: Beat Jet Lag After Long-Haul Travel

    After a long-haul flight, why can a child feel exhausted during the day but suddenly become wide awake at night? Why might they struggle to sleep even when they are clearly overtired? Why do mealtimes feel off, and why might hunger show up in the middle of the night? In this episode of The...

  10. 33.Not Just a Mess: What Toy Cleanup Reveals About a Child’s Growing Mind

    Why can a child clean up toys at preschool, but leave toys everywhere at home? Is it a lack of discipline, or is something deeper happening in the preschool brain? In this episode of The Scientific Parenting Diary, we start with one ordinary family struggle: toy cleanup. From there, we explore…

  11. 32.Preschool Immunity Series (5): The Boundaries of Immunity

    In this final episode of our preschool immunity series, we are not adding more strategies or new information. Instead, we step back to examine a more fundamental question: where are the boundaries of what can actually be influenced in a child’s immune system? After understanding how immunity...

  12. 31.Preschool Immunity Series (4): Common Dietary Misconceptions About Children’s Immunity

    Many parents put significant effort into “boosting” their children’s immunity — through vitamin C supplements, fruit, soups, and various health products. But an important question remains: Are these efforts actually helping? In this episode, we step away from simply askingwhat to feed, and…

    more
  13. 30.Preschool Immunity Series(3):Why Children Respond Differently

    In the same season, the same classroom, and the same environment, why do some children seem relatively stable while others appear more reactive? We often describe this difference as “weaker immunity” or “poor constitution,” but that explanation is often too simplistic—and can easily lead to...

  14. 29.Preschool Immunity Series (2): Spring as a Challenge for the Body

    As spring arrives, many parents notice something subtle but unsettling—their child’s body seems to “change.” There are more fluctuations, more visible reactions, and sometimes it raises a natural concern: is something wrong with my child’s immunity? In this episode, we take a step back and look…

    more
  15. 28.Preschool Immunity Series (1): Understanding the Immune System of Preschool Children

    When parents hear the word “immunity,” they usually do not think of it as an abstract biological concept. Instead, they think of very specific moments in daily life: a child starting preschool and suddenly having more runny noses, coughs, or occasional fevers than before; or those times of...

  16. 27.How Parents Shape a Child’s Long-Term Win–Lose Mindset

    In a child’s world, winning and losing are never just about the outcome. What truly matters is the meaning they attach to losing. In this episode, we take a long-term developmental perspective on how parents shape a child’s win–lose mindset during the critical transition years of 4 to 7. We…

    more
  17. 26.Parenting in the Moment of Loss

    In this second episode of our series on preschool competitiveness, we shift from understanding to action. Last time, we explored why children around ages 4–6 suddenly care so deeply about winning and why losing can feel overwhelming. This episode brings us back to the game table—the moment when...

  18. 25.How Children Experience Festivals

    For adults, Lunar New Year often represents culture, tradition, and heritage. For preschool children, however, it is experienced very differently. They may not grasp the historical meaning behind the holiday, but they deeply remember the atmosphere—the colors, the food, the sounds, and the...

  19. 24.When Winning and Losing First Begin to Matter to Children

    Around ages four to six, many children suddenly seem to care deeply about winning and losing. A game that used to be fun can quickly turn into tears, frustration, or angry protests of “It’s not fair.” When adults see this, it’s easy to worry: Is my child becoming too competitive? Are they a sore...

  20. 23.Children Growing Up with Mandarin in an English World(2)

    For preschool children growing up in English-dominant environments, understanding Mandarin often comes much earlier than speaking it. In the previous episode, we explored why this is a normal and healthy stage of bilingual development—not a failure on the child’s or the parents’ part. In this...

  21. 22.Children Growing Up with Mandarin in an English World (1)

    Preschoolers growing up in an English-dominant environment often understand Mandarin far better than they speak it. Many parents wonder: If my child understands Chinese, why do they always answer in English? Are they really learning the language, or just passively hearing it? In this episode…

    more
  22. 21.How Children Experience Adult Anger and Reasoning

    Many parents have experienced this moment: you’re upset, trying to explain what went wrong, and speaking more firmly than usual—when suddenly your child goes quiet. They stop responding, stop moving, and seem to shut down completely. It’s easy to interpret this as defiance, avoidance, or refusal…

  23. 20.A Smarter Way to Use 529 Plans in California

    When it comes to education planning in the United States, the 529 plan is often presented as a universal solution. But for families living in California, the real question is rarely whether to use a 529—it’s how to use it without making costly mistakes. With no state tax deduction, a high number…

    more
  24. 19.Understanding the 529 Plan: Risks, Strategy, and Long-Term Growth

    For many parents, questions about a child’s future arrive long before the child is old enough to ask them. Even while our kids are busy learning letters, making friends, and discovering the world one tiny step at a time, we may already be wondering: How much will college cost? Should we start...

  25. 18.AI for Kids: How Parents Can Guide Early Understanding

    AI is no longer a distant concept—it’s in our living rooms, our phones, and even our bedtime stories. Smart speakers answer questions, apps generate drawings, and story tools respond to a child’s imagination in real time. But when a four- or five-year-old encounters AI for the first time, the...

  26. 17.A Child’s World of Fairness: How Parents Shape Early Fairness

    Young children often say, “That’s not fair,” whether they’re sharing snacks, taking turns, or simply observing how adults make decisions. But for children around ages three to six, fairness is not a moral principle or a rule-based judgment—it’s an emotional experience. Fairness, at this age, is...

  27. 16. After Trick-or-Treat: How to Help Kids Step Out of the Sweet Trap

    After Halloween, the candy pile at home looks endless—and while your child’s smile is sweet, you might already be wondering how to handle it all. In this episode of The Scientific Parenting Diary, we take a calm, science-based look at what happens when kids consume too much sugar and how parents...

  28. 15. When Grandparents Raise the Kids: Love, Gaps, and Lessons from Chinese Families

    In many Chinese families, grandparents play a central role in raising young children — but “grandparent caregiving” is far more complex than simply helping out. It’s an act of love that bridges generations, yet it also reveals gaps in communication, differences in discipline, and hidden emotional...

  29. 14.Public vs. Private Elementary Schools: Community, Values, and Belonging

    In this second part of our deep dive into public and private schooling, we move beyond structure and statistics to explore the “soft environment” that truly shapes a child’s growth. What kind of community helps children build confidence, empathy, and a sense of belonging? How do diversity, class...

  30. 13.Public vs. Private Elementary Schools: What Parents Need to Know

    For many parents, choosing between public and private school isn’t about ideology—it’s about understanding what truly differs beneath the surface. In this episode of The Scientific Parenting Diary, we break down the structural, financial, and regulatory contrasts between U.S. public and private...

  31. 12. More Than Hobbies: How Interests Shape Friendships and Self-Worth

    In early childhood, interests are never “just hobbies.” They are often the bridges through which children enter the world of peers and the mirrors that help them understand themselves. A child who joins a soccer team may, for the first time, experience the meaning of teamwork and competition....

  32. 11. When Interests Hit a Low: How Parents Can Support Kids Through Struggles

    Children’s interests don’t grow in a straight line—they rise and fall like a heartbeat. One day, your child is eager to swim, paint, or practice piano, and the next day they sigh, “I don’t want to do this anymore.” For many parents, these moments trigger worry: Is my child losing focus? Have they...

  33. 10. (Extended Bonus Edition) From Spark to Growth: A Parent’s Guide to Supporting Early Childhood Interests

    A child’s interests are like windows into their inner world. Some kids can spend hours drawing, dancing, or singing, pouring emotions and imagination into their creations. Others are fascinated by bugs, rocks, or little experiments, showing a natural curiosity about how the world works. Some…

  36. 8. Shy, Clingy, or Just Warming Up

    Is your child slow to warm up in social settings? Do they cling to you in new environments, avoid eye contact, or resist sharing toys with others? You might hear comments like “too shy,” “not social,” or even “poorly behaved.” But is that really the case? In this episode of The Scientific…

  37. 7. Impulsive, Hyper, Out of Control? Or Just Not Ready Yet?

    Your preschooler won’t stop moving, keeps interrupting, grabs toys, pushes other kids, and ignores the rules—are they just being difficult? Or is their brain simply not ready yet? In this episode, we take a closer look at some of the most misunderstood behaviors in young children: Constant...

  38. 6. Lying, Backtalk, and Saying ‘No’: Why It Happens—and How to Respond
