I can't continue like this for much longer, can anyone give me some advise?

[M78]

my 20 wo DD2 sleep has deteriorated to the point that I feel I am going to loose my mind. We have a routine of bath, massage, bottle of ebm at 6.30 pm then dh cuddles her to sleep, which does not take longer then 5min and she then sleeps in her cot ( which is attached to our bed) until midnight/1am when i feed her and after that we end up co-sleeping, which i would not mind at all, but all she does is coming on and off the breast pulling and crying, she will then sleep for 30 min and then it all starts again until 6am when i get up. What is going on? She has never been a good sleeper but at least she used to settle in between feeds, she even slept through from 7am to 7pm for 3 wks last month! I can't go to sleep before 11pm , so at the moment i get only 3 hrs of broken sleep a day. DD2 only naps 20 min 3 times a day so no chance of having a nap myself. My parents live abroad and have no help here. What am i doing wrong? I can't continue like this, i am starting to resent her....

Could you try putting her back into her cot after her midnight feed? If she is sleeping for longer stretches in her cot, then it could be that you are disturbing her when co sleeping, and then she is feeding for comfort to get back to sleep, rather than hunger?

Hang on in there, it does get better

I have actually thought about the fact that I could be disturbing her when co-sleeping, I will try tonight to put her back in her cot and see if she sleeps for a bit longer....

So she goes to sleep at 6:35 and wakes 5.5 hour later?

Put her to bed at 12 when you go, you'll get a straight run of 5.5 hours sleep. If you go to bed for a couple of hourse before that whilst your dh entertains her you'll get even more.

This isn't a problem it is NORMAL, I promise. Just concentrate on surviving.

She might be teething, you could try a teething powder before bed?

Just read another thread earlier and the mum said that "It's very common for babies to have a period of 'sleep regression' between 4-6 months". Think she must be right because its unbelievable the amount of mums on here with babies who are suddenly not sleeping! At least we have company. lol I am very lucky and my hubby and I take it night about. We have decided its easier to bring DD into bed with us. The person whose turn it is to sleep goes to the other room.
