Tom usually self-settles well, and recently has started using thumb-sucking as one of this self-comforting methods (he doesn't do it all the time, but he is doing it quite often). As he usually self-settles, on the occassions when he is overtired and can't easily get himself to sleep (unfortunately with a toddler as well he can't always be put down at the first tired cues), it is not easy to get him to sleep. He doesn't feed to sleep (if he does fall asleep on the bb he wakes up a couple of minutes later). He doesn't go to sleep if he's being rocked or patted etc. He does have a Peace Baby CD which helps but is not enough on its own.

Sometimes when this happens, I can put his thumb in his mouth for him and he'll stop crying and drift off to sleep. I am not a fan of thumb sucking as I am worried he won't grow out of it later. Do you think I am doing the wrong thing by helping him thumbsuck? Should I try and find another way? Or do you think it is ok? I'd appreciate your opinions. Thanks. (ps he won't take a dummy).
