We had four sessions with CO, didn't make any difference and DD hated it, screamed throughout.
I'm pretty certain I know why she has bad nights - it is the lack of daytime naps.
Until she was 7 weeks old, she napped well, we had a bedtime routine, bf and awake to her cot where she would drift of easily.
At 7 weeks her naps started to become shorter - down to 40 min and by evening she would be overtired and hysterical and would not let me to put her down. That's when I started feeding to sleep as I felt I hd no choice.
I tried everything to extend her naps - sling, car, white noise, putting her down as soon as she showed signs of tiredness, playing lots so she would get tired. It got worse and now we are down to 30 min.
Tho only thing that sometimes works is lying down with her, feeding her to sleep and then popping my boob back in her mouth every time she starts waking. On the days I manage to get her nap like that for couple of hours we have much better nights.
Tried bottle of EBM this morning when she was in good mood and appeared rested, she went berserk so gonna have to stick to bf for now anyway as I have a feeling making her to take bottle would make things worse.
