What size diapers are your lo's wearing now? My son is 12lbs and I feel like his size 1 diapers are too small now and I put him in a size 2 today. It comes up a little high like right above his belly button but it's way easier to close now. Wanted to see what other moms babies are wearing. He wears the pampers brand btw.
