@jerryklasic Clothing fits different babies differently, I don't think that's a surprise to most parents. Just like all other shapes of humans. I didn't find it jarring to have a few pieces of NB that he never wore, but it was nice to have them in case. I know his cousin ended up wearing them for a few months when we sent them along. (My guy was 9.5lb, lol. He was fitting 3-6 month clothes by 3 or 4 weeks.)
As for gender neutral clothing, it boggles me that isn't the default place people go to. Kid doesn't care, and I don't understand the value of heavy gender signalling. Wear what you want, but also, no one is going to care if your boy wears pink stuff.
Snaps > zippers, every time. Snapped clothing contours to the kid way better, it isn't hard, and I seem to get another few weeks of fit compared to the zippers that always do that weird curly popping thing. And snaps you can keep snapped where you want them, vs. having to remember which sleeper has a two way zip or not.
But hey, that's why there's loads of options!
