My 4 year old. He won't poop in the potty. Didn't talk till 2. Never held a pencil right till a month ago. And now he can write his name. Well sort of. His e is a little crazy and he does not dot his i. I do have to tell him the letters. But he wrote it by himself. I am happy. We will keep practicing though. He just turned 4 so I don't expect perfection.
