I tried and tried to teach our daughter how to tie her shoes.. never could teach her.. Then one day she came home and told me Patrick at school taught her how to tie her shoes!! Thank you Patrick! Maybe have a friend come over to work with him.
Just have him practice. while he is watching TV..
The button deal, again have him practice. when our daughter was 5, I realize i had neglected having her work on her "fine motor skills'.
So we had her,hang and then button all of the shirts that came our of the dryer.
All of the jeans, we had her zip and button them also. Then use clothes pins to hang them on hangers.
I gave her clothes pins, to use to pick up and move things.. She was only to use her pointer finger and her thumb. It was fun t see what she could carry, even we would play this game. Paper, magazines, pens, toys. towels..
I had her separate the coins out of piggy banks, Then had her stack them in plies. Only using her thumb and forefinger.
I had her connect all of the paper clips together to make them into a long chain.
I had her roll out little balls of playdough, using only her thumb and forefinger and line them all up. Then I would have her quickly mash each one only using her forefinger. We would race to see who could do this the fastest.
He just needs to build up and get used to using his fingers for these tasks.. Then he will have some strength in his hands and fingers to do these things.
