my 9 month old is suddenly waking up 2/3 times a night when his used to sleep right through (12hours) , he seems really distressed,he doesnt seem hungry, and as soon as I pick him up and take him into our bed he is fine again and goes straight back to sleep. could this be separation anxiety and if so how should I react to him. I really dont want to get into the habit of him coming into our bed.he is still in our room so would it be better or worse to move him to his own room? any advise would be really appreciated thanks
