My son is 3 1/2 years old. I am a single mother. My son is academically very bright-he memorizes street direction within 1-2 trips, he knows his right from left, he can spell 3-4 letter words, he memorizes songs and book within a few times hearing/reading them. He has always preferred books to toys. He is very emotionally intelligent-he is extremely empathetic and states, while crying or upset, that he is mad/sad/worried/scared. However, he is not potty trained. I have been trying for about 6 months. He will use the potty at preschool, but refuses to use it at home. And he does not seem to think for himself. His conversations are broken and littered with lines from books, songs, and tv. They do not make sense. He can't finish a thought. The other children at his preschool seem so much more advanced with their interpersonal/social/communication skills. Not many of the children want to play with him. He yearns so badly to have friends. When he's at the park, he stops and stares at kids coming in, almost like he's hoping they'll come up to him. I tell him to talk to them, introduce himself, and he does, but when they start to play, he just imitates them. He doesn't seem to want to show his own personality, which I know he has. It's almost as though he's too innocent. Or maybe just immature. I'm wondering if it's a developmental disability. He is so sweet and so smart in some aspects, but so completely behind in others. Any advice or insights? Please
