I'm sorry to bore those out there who have read threads like this 100's of times, but I am a little concerned.
My DS is 18 months old, and the only word he says is..."Tigger"....ALL THE TIME.
Occasionally he utters "bye-bye", but other than that it's unintelligible blabbering.
He's really active, and has no problems with physical development. He also knows body parts to point at, and various objects around the house to point at.
I'm just worried he's behind with his talking...
