20 month old ,

Suddenly for the past week now my 20 month old will wake up screaming 25 min into nap and nothing I can do will get him back to sleep . Cry it out will go on for a hour . And bedtime is the same now till eventually he’s so exhausted by midnight he sleeps

Nothing changes his schedule is 8:30-7:30

Nap 12:30 for about a hour

It’s like he’s out right protesting all sleep right now
