My son is 17 months old and is a drooler too (he's got lots of teeth and has been drooling pretty much since birth). I asked the doctor about it a couple weeks ago and she said everything else (eatting, talking, etc.) is on track and that some kids are just droolers. Congrats, we got lucky and got a drooler. :-) I'm trying to be positive. Good to know that it will eventually end. Another mom told me that blowing a whistle can help and also reminding him to close his mouth will help him to remember to swallow (he drools more when he concentrates).
Good luck!
