I've mentioned this before, but Blake doesn't pronounce the "th" sound correctly. If it's at the beginning of a word, it's either an "f" or a "d" sound.
Examples: over dere, free, firty, dat
Rob and I have been working with him on a few specific words so that he's aware of the correct pronunciation and aware of how to make his mouth form the words. Ounce of prevention (watch my mouth) is worth a pound of cure (speech therapy just doesn't sound fun). He's been catching himself and correcting himself, especially when counting:
B: One,two... THa-ree, four, five... (and on) twenty-one, twenty-two, twenty-free... twenty-THa-ree, twenty-four, twenty-five, twenty-six, twenty-seven, twenty-eight, twenty-nine, firty-one, firty-two, ONE HUNDRED. One hundred and firty-two DOLLARS.
I think he's going to be an accountant.
