My almost 21 month lo has been doing wake up around 7 nap 1230-230 asleep by 730 but he’s resisting his naps lately. Mostly it’s on days when big brother is home but lately he’s not falling asleep until 1 and only sleeping 1-1.5 hours instead of 2. When he wakes anytime after 230 he’s cranky and it actually takes him a while until he’s ready to get out of the crib not sure why. It also takes him about 30 mins to unwind in crib at night no matter what time he goes in. Tonight I tried a later bedtime of 730 and didn’t fall asleep until 8! I feel like Im always quick to change up his routine when things get wonky but sometimes it backfires.
