Bear in mind that obstetricians like to define any baby that looks/feels to them to be over 7lbs as a "good sized baby". I was told this when I was pregnant with both of my kids who weighed 7lb3oz and 8lbs at birth. Very "average" sized little citizens

Your baby is the perfect size and just the size it's meant to be You didn't "do" anything except give it a safe and healthy environment to grow in.

It's perfectly normal to feel like you're running out of room in the third trimester...even women carrying 6lb babies feel like this. It's not just a baby in there remember - there is a big placenta and a few litres of fluid too. No wonder it feels like you're running out of real estate .
