We have recently done sleep training and night weaning and it's starting to go well, however for the last week, lo has been waking up between 1-4AM and when he does, he will be up for 2-3 hours. We settle him every 5,8 then 10 min and repeat 10 min intervals until one of them he starts to drift off. Once he goes back to sleep he usually sleeps another 2-3 hours until he wakes in the morning and I feed him.
Any ideas what might be causing this / anyone had anything similar and got over it?!
