Our 22-months old still sleeps in a cot in our room, next to our bed. Although at some point in the night he’d cry and we’d take him into our bed, this worked well until recently. We put him in his cot at 7.30pm, laid down as well and he’d fall asleep almost immediately. For the past 4 weeks, that’s not the case anymore. He refuses to go into his cot and wants to be in our bed instead, but there he plays with us and won’t sleep. It’s a 2-hour battle each night until he finally sleeps around 9.30pm. In the morning he gets up at 6am and he does one nap, which I tend to cut at 1:15min but nursery will not wake him and he naps for 2h.
I realise that this is my own doing and we should have moved him to his own bedroom at 6 months old like every sane person does. What shall I do now, how can I get him used to sleep on his own at this age?
