Posting for traffic. My previously good sleeper has suddenly woken tonight at 10pm and gone crazy. Endless screaming , it’s horrendous. When I go in he carries on no matter what I do, cuddle, stroke, talk etc. He can’t possibly be hungry as bad usual large dinner. No temperature. It’s literally been going on 1.5 hours now, never happened before. I have a meeting at 8am and I am so stressed. Nothing is settling him. I can’t cope with this any advice please
