DS is 10 months. Following his hideous four month sleep regression we worked really hard on his sleep and, with a big dollop of luck, he learned to go to sleep by himself in his cot for naps and bedtime by six months. Amazing! He has a dummy and comforter.
The past week all hell has broken loose. The naptime or bedtime routine involves us kissing him, saying sleep well and leaving the room. He has decided to add inconsolable screaming at this point.
Calming him doesn't really work. He either continues to be upset anyway or tries to play. He can't be cuddled to sleep. Eventually he ends up exhausted and passes out, normally then only napping for half an hour. It's taken two hours to put him down for a nap at points. Sitting in his room results in him trying to play and throwing dummies at us. Earlier naps haven't helped, or later ones.
How do I help him through this stage?!
