At about 15 months, here are the words Henry can say:
1) Deh!--what he says when he throws something (like the Burgerville french fry he pitched over the back seat of the car and into the trunk this evening)
2) Mama
3) Ba-baaaah!--what he says when he wants food (usually Ritz crackers)
4) Dah-jee--his word for "doggy" and other 4-legged creatures
5) Eh-oh--his latest word, a variant of "uh oh"
