I went to get my 18 month old son up from a nap, and found he had thick white foam around his mouth and on his dummy. I've never seen this on anyone who hasn't had a fit/ seizure, can anyone shed some light? I rang the doctors and he just said to keep an eye on him as he can't say one way or the other whether it was a fit or not but thinks it's likely that it was. I'm worried that this will become an ongoing problem if it was a fit, and although irrational, I'm always afraid I'll find him not breathing when I go into check on him. Please help put my mind to rest...
