Is second baby usually bigger than first?

Morning all.

I’m 31 weeks pregnant with a baby boy. My daughter was born at full-term and was 8lb 7oz - she wasn’t chunky at all just had very long limbs! 😊 I’m 5ft 3in and when not pregnant am a size 6-8 and I remember a number of people being surprised at my daughter’s birthweight.

People are now saying that the second baby is usually bigger than your first and that boys are bigger (or have bigger heads) than girls, which makes me feel a little nervous! Just wondering if there’s any truth in this? Would anyone like to share their experiences?

Thank you! x

My first baby was nearly exactly the same weight as yours (8lb 8oz) and my second was exactly the same! So not always...

My first was a girl born at 40+11 and was 8lb 8oz.
Second was a boy born at 40+10 and was 7lb 14oz.
So second babies/boys aren’t always bigger.

My first (girl) was 40 weeks exactly and 8lb 4oz. Second (boy) was 38 weeks and 7lb 14oz so i guess it depends. I think he would have been bigger than my first if he got to 40 weeks though.

8lb 5oz followed by 9lb 7oz. No way I'm risking a third!

Two girls, both born at 38 and a bit weeks, naturally. DD1 was 6lbs11oz, DD2 was 7lbs7oz. So a little bit bigger, but in the general scheme of things both quite light.

DS1 was 9lb15 so I really, really, REALLY hope you're wrong! I'll find out in May.

My two were
DD1 8lb13oz @42w2d (induced)
DD2 8lb11oz@38w5d (spontaneous)

Obvously DD2 would have been bigger if she'd made it to the same gestation as DD1, but I'm convinced that's why she came so much earlier!

You're not birthing Russian dolls or something.

My two boys were born with 1oz difference in weight... please don't believe any rubbish about boys having bigger heads?? I think some people enjoy telling horror stories about giving birth!! A lot of people told me second birth is easier and I found that to be true, so try not to worry!

DC1 was 10lb 3oz at 39+6
Everyone was holding their breath to see what DS2 would be, especially when I went overdue
He came at 40+5 at 8lb 8oz, which to me seemed tiny!
I remember they put him on my chest and I said oh my god! Is he ok? He’s so small!
