Hi there

Sorry if this is the wrong area I couldn't seem to find one on sleep!
Just wanted to post to get some help/ideas/sanity on what to do about my little girl
I'll give you the history first
Sleeping was going really well but we had a hanging bassinet and had to rock her to sleep each time, except in the mornings as she would usually just play and fall asleep on her own. We were also wrapping, which she would fight like crazy but then it seemed to work by lately she had been out of the wrap by morning.

When she got to 16 weeks all of a sudden over one night everything stopped working. She got hysterical, would punch her way out of the wrap and as soon as we would start rocking she would start screaming more. In the end we put her into a sleeping bag which she hadn't used before as we were just unable to wrap and finally after 3 hours she went to sleep exhausted. This has now been going on for over a week. We do have a rough evening routine involving a shower with dad and quiet time. She used to go to sleep for the night any time between about 8:30 and 10:30 and would sleep usually til 5-7am which was great. We also would use shhhhing as well.

Anyway over this week we have been trying everything. We have now moved put her in the cot instead as it seemed every time her head hit the bassinet she would know we wanted her to sleep so would go nuts (she is in our room).
Now I have discovered that she does tend to have a cry before she goes to sleep as she started doing it in the pram so during the day sleeps I have found I can leave her to have a cry and usually she falls asleep on her own, this doesn't appear to work at night as she gets hysterical and we aren't comfortable with leaving her for long as this stage.
The other thing is I have started doing a basic Tizzie Hall routine as DD was following this roughly anyway during the day. Discovered that she does need a pram nap at the 4:30 mark whereas before we would try and keep her up so we could do all her night time routines like shower etc. So yesterday we took her out, she had a good 30 min sleep in the pram and then we got her down (with some struggles) by 7pm. But she is awake again within the hour and then we had to bring her to the lounge to calm down (she wouldn't calm in the bedroom) have a feed and then take her back to bed when she was tired. Then I shhhh'd and patted (which didn't used to work) and she calmed but stayed awake - I ended up doing this for an hour and a half and then she started crying again and it was time for another feed.
So you know her naps are usually good, she wakes a 7am then goes back to sleep an hour later (we have been trying to extend this to 9am and are just about there) then up for two hours and back down for about an hour and a half and now we do the walk at 4:30. Sorry this is so long, I am just completely lost as to what is going on and how to deal with this. thanks for your time
