My 3 yr.old had foam at the mouth while sleeping. It was white and frothy. Snoring loud and heavy breathing. Tonsils look big and very pink. No fevers, no headaches. Bad dreams. ( I think) She moving a lot during the night. Sometimes wakes up, sits up then goes back to sleep. Past two nights heavy breathing and very loud. The foam was just last night. Oh, and she has very bad breath in the mornings.
