I stopped liking onesies when Leo outgrew them really fast. we could make them snap, but he'd get that really low neckline even though it wasn't that much of a stretch to get it to fit together at the bottom. once he got to the size that he could wear t-shirts(why can't they make them in smaller sizes??) it was so much easier to dress him and keep his clothes clean without doing so much laundry - don't have to change the shirt when a diaper leaks. a lot of his stuff is still the snaps, so I went looking and found this tutorial on fixing that and it worked great! I'm not good enough to get it done in 5 minutes like she was, but I think I managed in 10.
