Diaper size

brooke • girl mama💗💗

How much do your babies weigh and what’s their height and size diaper? My daughter is probably about 18 lbs now and she’s 27 inches long and she’s wore huggies/pampers since she’s been born as they are the only diapers that work for her. I’m finding her to be too long for the huggies diaper (snug and dry) and it’s getting to be an awkward fit and she leaks through sometimes. I want to try sizing up to size 4 but scared they will be too big?
