Until recently, my 6 year old son has been a very good sleeper, sleeping in his own bed, and getting a good nights sleep, 10-11hours each night, however, just recently, after he has been asleep an hour or so, he starts screaming and coughing and finds it hard to settle, this can go on for a good few hours. He wanders sometimes during this, and has little recollection of this in the morning. It is getting rather an issue as it disturbs he rest of the family, and there is no reason we can see for it as he is his normal healthy self during the day.
We thought maybe it was due to the lack of routine, as it is now the 6 weeks school holidays and he's not at school but we have mostly kept up his normal bedtime routine
