Just when you think you know what you are doing... it all goes tits up again.
DD turned 6 months yesterday. Sleep has been up and down, but mostly good. She started sleeping through most nights from about 18 weeks, as long as I got enough calories into her during the day. That got disrupted by various colds (I have a 3 yr old too) but when well she was mostly sleeping through or waking very briefly, crying out once, and then going back to sleep again a few times a night. She sucks her thumb and so goes to sleep by herself.
She had a bad cold a couple of weeks ago and was struggling to sleep, so I ended up taking her into bed with me a few nights at around 3 (having already fed her and tried other settling methods). This seems to have created some unwanted associations and now she often is waking up sometime between 1 and 3 and being awake for 2 hours or more. She finds her thumb but doesn't go back to sleep with it, so we get short bursts of crying, followed by thumb sucking, followed by more crying. Feeding her or not feeding her makes no difference. If I take her into bed with me she'll go to sleep within 10 minutes, but if I don't nothing else seems to settle her.
I don't want to co-sleep, so what can I do to change this? It doesn't seem to be hunger as feeding her makes no difference. It is also not every night - some nights she sleeps 7-5 (which is brilliant I know). So I'm left with a choice of it being caused by
- separation anxiety (although she sleeps in a cot right next to the bed)
- not being able to self settle (though she obviously can some nights
- daytime sleep needs adjusting (currently 3 or 4 naps, usually 45 mins although an occasional 2 hour one sneaks in there. Total around 3-3.5 hrs)
- have created unwanted sleep association which needs breaking (how?)
Help!
