yeah i DO remember that!! my son who is now 2 1/2 and my daugter who is now 6 both did that. it seems for them it was a phase. but good greef it drove me NUTS! i thought that they were going to harm their teeth. but i did talk to my doctor about it and they told me that it ws normal. it did stop when my daughter was about 23 monthes and my son about age 2. i think that it is just one more thing that they can discover. don't worry i am sure he sill stop. sometimes when my son did that i would give him a teething ring to give him something else to do with his mouth. he took it sometimes but not much. but you never know maybe your son will like the idea.
