I posted a few days ago about my DS (2 in March) waking up a couple of hours after going to sleep and inconsolably crying for a while.
This has now gotten worse - he is waking up every 30 mins or so and inconsolably screaming for about 10 mins, nothing soothes him at all. He will do this all through the night and won't really sleep in his own bed now.
I've just gone back to work today and DS was supposed to be going for his first day of nursery but DP is having to take time off as I'm not comfortable with sending him to his first day of nursery when he's so exhausted and not feeling 100%.
I'm trying really hard to be patient and understanding but guiltily failing
Does anyone know what this could be because I feel at a loss?
