So last Sunday my son started a great sleep schedule and would sleep till 8:30am or later, he'd only stir to nurse overnight and would never wake up if he was fed when he started stirring. Well I bumped him up to size 3 diapers for night time and he's peed himself the last two nights and last night woke up at 4am and today at 5 😔 I don't mind getting up but I finally got him on a great schedule and these new diapers seem to be the downfall. They fit great but the material is different from the size 2 Target diapers that I've been loving. Does anyone who uses/used Target diapers know why the 2s and 3s are made different, these seem less absorbent?
