Baby refuses to sleep in her bassinet

Charlotte

My daughter is almost 4 months and has broke out in this awful rash on her neck which I’ve included pictures of (I’ve been to the doctors once and I’m going back again tomorrow) she absolutely refuses to sleep in her bassinet at all out of nowhere and no matter what state I put her in it she will wake immediately. She nurses pretty much all night and I’m sore and tired and I want to be able to get her to sleep in her own safe space so we both can have a good nights sleep. I don’t know wether it’s a 4 month sleep regression or something to do with her neck.

In regards to her neck she still feeds just fine and she is quite happy in herself although it does seem to be itchy as she keeps rubbing around her ear. And it is being bathed and a barrier cream is being applied as a pharmacist and doctor recommended.

All advice would be much appreciated thank you in advance.
