Choking in sleep

[Butterflies27]

My dd is 3, she suffers with chest problems and since her last bad episode we haven’t got her back in her own bed. She is sleeping in my bed this means I am having to go to bed with her at 8pm. I have noticed for a while that dd chokes a lot in the night/appears to chew things when asleep more so when on her back. She has a dummy but not always in when this happens. She can be sleeping peacefully then will start choking/coughing -is this normal? My dd has very large tonsils and had a sleep study last year for sleep apnea which showed nothing, just wondering if any other toddlers do this or if it’s something I should get checked.
Many thanks

Could she have reflux? I know she's 3- but I developed it when I was in my 30s
