At 18 months, by medical standards, he should be saying 10 words.
Now he may not meet all of the physical milestones - but my boy has his 10 words down!
He knows Up, Down, Buh-bye, Uh-oh, NO! (my favorite...or not), Yay!, Yummm, WOW! Mama, Dada, Poop (a close second favorite), Ball, Puppy, Hot, Bubble, Outside, Hi!, Hello, Pop!, Auntie, More, Home, and Bath.
There are quite a few more - but I'll spare you. Point is - I'm proud, and I had to share it with you all!
He also sings "E-I-E-I-O" (see below), and "Twinkle, Twinkle".
