Good morning my fellow NL,my little son of 2yrs and three months old is very good at Tom gold run and another game Angela that whenever he plays I can't just but marvel at the way he plays them.
Should I let him continue or find him another thing to occupy him,like he will be crying that he must play these game whenever he sees my phone or his mummy's, I don't want it to be an habit ADVICE PLEASE

Teach him to manage it. Game playing can be a great career. Let him have set times when he plays and other times when he does other stuff.
