I know this board is full of parents who have way worse sleep issues but I'm really stumped by this and need some advice.
DD is 17wks and has been sleeping through 9-8 with a dreamfeed at 11, an increasing proportion of nights since 10 weeks. She was doing it almost every night until last week when she suddenly started waking at 1.30-3am for no obvious reason, just wide awake and either squirming from skde to side or just "talking" to us. She's generally awake for 2-3 hours. As she's happy I just am at a loss at what to do. I don't believe she's hungry when she wakes, but usually after 2.5 hrs of talking and squirming she is, so I BF her and then she either slowly drops off again or has a second wind and is wide awake for another hour. Unfortunately she still wakes for the day at the same time.
She's in a bednest bedside cot. We've tried just shushing her, laying with a hand on her chest or tummy, bringing her into bed with us, going into the nursery with the lights on, or off, putting her lullaby nightlight on. DH has had a night with her and eventually came to me in desperation after 3.5 hrs as nothing would settle her. Anything we do seems to wake her up quicker but if we do nothing she still eventually fully wakes and then cries because she's bored. She does have a dummy at night but I'm unsure if this has anything to do with it as I am right there to put it back in for her. (This is the reason I haven't tried putting her in her own room).
The only nights she didn't do it were when we were away for a weekend with friends. I assume it was all the new things to see and hear but it's just not feasible to move to a farmhouse in Dorset!!!
It feels like the end of the world at night. I know about 4m sleep regression but assumed she's be waking hungry or unhappy if it was that? Tonight she's been awake since 3, ive just fed her in desperation and she's now lying there laughing and talking. Please help!
