Croix kept saying milk with a p sound at the end, like milp. So we worked on saying M-I-L-K milk, like c-c-cat, milk. Because he says cat fine, so we know he can make a K sound. Well now Croix says milt, with a T end like cat ends in a T. He's also started adding a T sound to all sorts of words! So now we say M-I-L-K like truck! We'll see if that works!
PS milt is actually a word, and it's a little gross. But not inappropriate don't worry if you want to look it up.
