People make all sorts of thoughtless comments. Someone said a similar thing to me, 'wow you're small! I hope nothing's wrong!'

So while I knew in my head that things were okay, I also was uneasy.

Here are some reasons why people carry small. I'm sure people will be along to add more.

- you're tall (more space for baby to fit without pushing outwards)
- you or your partner are small (so the baby might just be small like it's parents!)
- you're carrying bub more against your spine
- it's your first baby (stomach muscles hold everything in very efficiently)
- you were very slim/underweight to start with

Anyway - the bub where people commented on my size - ended up being 9.4lb! That's not small really. I just was slim, and it was my first baby.
I know it's easy to worry, but remember that if your bub was too far behind dates (mine would be behind, then have a growth spurt where I felt extra tired and then would measure ahead of dates), then your ob would have said something. Take comfort in the thought that pregnant women everywhere get these silly comments.
