Hi Sophie,
First off big ((hugs)). So, can you help me with a couple of things - it might help to see what's going on.
1. Can you post your LOs day in EAS format?
2. Any sign if teeth
3. How long has your LO been fighting sleep?
4. Why did you your 5yo need to go to hospital for sleep training?
Sorry for all the Qs - it's just difficult to help without having a picture of things iykwim
