If you limit switch / iPad to weekend I’m sure he will start to play with his toys , I know it’s hard!
we have iPads only on weekend ( and switch for 10 year old ) it stops the constant battle!
if your ds has poor fine motor skills , the best things to help him are play dough , kinetic sand , peg boards . If you sit down with him at first you should be able to leave him to do it himself .
unfortunately my dd5 will not play by herself ever , so I have to find things that I enjoy doing with her 😂
For Christmas she got lightbright, brilliant for fine motor skills, it’s little pieces you put on a board that light up .
she also got an lcd writing pad which I think is her favorite thing she got !
My dd5 loves play dough , kinetic sand , any orchard games , connect 4, frustration , dominos , drawing , writing , any arts & crafts .
she also loves playing with lol dolls , play mobile , role play games - though she mainly plays with her friends /sister because I just don’t have the same enthusiasm for role play
She does watch tv during the week though , I need her to so I can get things done ! Generally about 45 mins in the morning and 90 mins in the afternoon/evening- depending on after school activities/ play dates
