Wow, your DS was a whopper! My babies got smaller.
Hehe yep hence my question...

It's really something that is totally random. There is no way of knowing if a subsequent baby will be bigger than the others. I wouldn't worry about it - what will be will be and if you've gotten a baby out that big before, then you can do it again.
I know its random... I know there's no way of predicting... that's why I asked for anecdotes!

I have complete confidence in my body to do its thing, TBH my labour with DS and his actual birth was much better than my labour with DD and her birth!

I was just curious

Anecdotally - looks like third babies get smaller
