Is she feeding ok? Enough wet and dirty nappies? Gaining weight ok? My LO was very fussy and wouldn't sleep and it turned out I wasn't supplying enough milk x
Is she passing wind and going to the toilet ok? If not what have you tried so far to help with this? Feeding ok? Can you not reach out to your friends to help out even for a couple of hours so you can get some rest? If not you need to speak to your health visitor for some advice and support
This is me just speaking from my own experiences, I'm really sorry you are going through this it must really be affecting your mental health especially with no support. Have you tried formula if breastfeeding? My first son was like this because it turned out I wasn't producing enough milk, he was settled and happy with formula (SMA). I've found both my sons slept more soundly swaddled than in the sleep bags. So formula and swaddling in a cellular blanket would be my things to try if you haven't already. Also going for walks in the pram the movement might help. Any of the white noise type stuff sometimes helps, there's playlists on Spotify. Try different positions when burping/ little and often rather than burping at the end of a big feed. Sleep deprivation is a form of torture - big hugs!
Honey I know you might not like this, but Co-sleep. I didn’t want to cosleep with my girl. I hated the idea. But it was the ONLY way she would sleep. There are so many safe sleeping articles online, especially by the lullaby trust, and baby will sleep for much longer stretches with you there. Hope this helps you and I am so sorry you’re feeling so terrible. Also, try infacol for the colic. Sending so many hugs and all of my support I know how hard it is, you’re smashing it💗💗
You might be doing this already but when putting her down lower her bottom down first then really slowly lower her top half and her head and once fully down keep your hand on her tummy for a while. This is less likely to trigger the startle reflux and wake them up. I had similar with my first and this made a big difference and really helped (before I learned this I was just lowering her head and bum at the same time). For colic Infacol and holding him so his tummy was laying on my forearm after a feed (Google colic hold) for a while or tummy time also helped us. I hope things improve for you soon.
this was my baby until i realized she’s cold.. she loves to contact nap so she’s used to being warmer!
She is on me 24/7 or cries even when just changing her nappy
