This has been going on for weeks now, on and off. My DS goes to sleep with his dummy and will sleep for a few hours in the evening. He is bf but gets a dream feed of formula at around 10.30pm to see him through. He will then wake at around 2am (this morning it was 1), not for food but just to spit his dummy out, suck his fingers VERY LOUDLY and grunt. It is never ending. I try to feed him but he just has a few sucks, dozes off and then cries as if I've taken him off - it's just a comfort thing. Even if he does fall asleep at the breast, he will wake as soon as he's moved and even if he isn't moved (we've tried co-sleeping), he will still wake and persist on sucking his fingers and grunting. I have spent hours with my finger on his dummy trying to keep it in his mouth so it isn't replaced by fingers.
He used to nap badly in the day but has improved vastly since we bought an Amby hammock. But, nothing works through the night. It's as if he's bored and just wants it to be morning.
Any advice? I had 2 hours sleep last night and average between 2-4 hours every day and it is starting to affect the relationship I have with my DH, despite us desperately trying to stay calm with each other.
