I don't know anything about dressing babies. But I can tell you that I have wayyyy too many NB onesies! Guessing from our many growth u/s where baby has been hovering around the 15th percentile (and has shorter legs), he might be wearing NB for a while?
Do boys wear cotton rompers in the summer? I'm wondering if I should get a few of those so I won't have to deal with onesies/pants when we go out....
(And does CDing affect the size they wear? Sometimes I look at these clothes and wonder how the heck a chunky CD butt is going to fit!)
