My 15 month old is so unpredictable when it comes to waking up. He sometimes sleeps till 6 or 615 with no wake ups. Mostly though it 4 or 430 andvI am currently doing cry it out. Within half an hour hes normally back to sleep. I put heating on early i have totally dark room. I am in contact with a sleep consultatnt wgo says iis coz he needs to drop hos mornong nap. I try and keep him busy. Yewterday he fell asleep at 11 30 but i woke him up quick as he was in buggy in then spent 40 mins crying till he fell asleep for his nap 1. Very unusual. Hes now woken at 4 350 and i doing controlled crying. Day before awale all morning down for nap at 12.40 slept 2 hours still woke early and had to do cry it out. He does go back to sleep but i want him to not wake especially if im putting all this effort into a sleeo schedule. Hes seems most settled when hes had a 10-15 car cat nap in morn then he seemscto naturally go off about 1-2ish for an hour or so. I dunno what to do. This is taking over my life and i am so tired iys hard witg my 4 year old. I just need to no why hes doing this!!
