Violent waking

[tararawlings]

My 2 yo has started waking in the night due to coughing. When I go in to check on him he becomes hysterical and violent. There is literally nothing that calms him down. He doesn't understand that it's still nighttime and will not go back to bed. We have tried sleep training and leaving him to cry but he will go for 2hrs + with no let up. Any advice is welcome. Thanks in advance

Maybe try a gro clock so he can see it’s still night time.

Also if you didn’t go in to him would he eventually come in to your room to find you? If so maybe leave him to come to you and then try the return to bed routine, it can be a painstakingly lengthy process for a few nights but it did work for us after 4-5 nights.
The key is consistency.

Why is he coughing?
Has he had a cold recently?

It might be that its scaring him that he cant stop coughing ir catch his breathe properly
