DH & I are off to do more baby shopping tomorrow - hooray! But, I just looked at my list (that I don't even know where I got from lol) and it has the following:

9-12 Newborn Bodysuits (I'm assuming 0000)
9-12 Medium Bodysuits (assuming 000)
9-12 Large Bodysuits (assuming 00)
4-6 Pullover Shirts
2-4 Cap & Booty Sets
6-8 Stretch Rompers
4-6 Cotton Rompers
3 Cotton Bottoms
Sleeper Sack
Hats/Beanies
Socks
Shawls/Wraps/Blankets

I'm alright with most of what all that means, but what's the difference between the bodysuit and the romper? And what size should I get a romper in? Feeling a bit clueless here
