My 10 month old screams alot..his grandmother made him addicted to mobile phones

A. It’s the worst addiction a child can have a child can actually have brain numbing and verbal delay and it can also affect the eyes of your child so please stop showing to the child even if the child is screaming your child involved into other activities games and toys and please strictly tell your mother-in-law not to show mobile to the child as it can be really very bad for overall development of your child specially mentally and verbally
