Hey mamas, what size is your 7 month old in diapers? My Baby is in size 3 I'm not sure but think he might need to go up to size 4. I just don't want to buy them and then be to big I usually buy boxes.
You can take them back if they don't fit but I'm pretty sure I moved my son up to size 4 at about that age, 7/8 months old and I think the size four was a tiny bit big at first but only for a few weeks then it was fine.
