Episode 151 - Big Babies, Small Babies: Understanding Size, Scan Accuracy, and Your Choices at the End of Pregnancy

In this episode, I unpack one of the most common concerns at the end of pregnancy: baby size. Whether you’ve been told your baby is “big” or “small,” this conversation can quickly lead to discussions about induction, monitoring, or caesarean birth.This episode breaks down what those labels actually mean, how accurate growth scans really are, and how these predictions can influence decision-making.
