Hi Fenalla, I understand your frustration. We do something similar at night, some nights Maggie will happily go in the cot for 3 hours and other nights she will wake every 40 minutes (normally half way through a show I was really enjoying). Other nights she will sleep really well if we keep her in the lounge with us, but we put her on a little mattress. So you could try giving a small mattress a go for a few weeks to see if she sleeps on that and then transition her to the bedroom.

I have also found that if I get her to sleep with certain music and put that music on in the bedroom as well, that sometimes she will sleep longer. Maybe something consistent like music, or a toy etc may help. Good luck!

The frustrating thing with Maggie is that she in not consistent, what she will do one week, will not happen the next. This week happens to be her wake frequently week.
