way too young

so is 20 months too young for a boy to start waking up saying his sister's best friend's name? i heard him in the monitor this morning saying "Ah-Ah-bee"...over and over. i think i mentioned in a previous post that we think he has a crush! and he's way too young to light up the way he does when he says her name! and definitely way to young to be doing the tongue action that he's doing with abby in this photo! maybe it's a good thing abby is moving....?! (btw, that is a popsicle they have between those tongues!)
