My son is a loving smart and outgoing 4 year old he’s usually in his own world but he likes to keep busy I work every other weekend and he has a daycare but some times I may need a back up

I need my son to be supervised he’s very technical and can operate his own phone I will provide toys and activities for him to do while he’s with you when it comes to his phone I just need him supervised on YouTube he watches YouTube for kids but I would like to make sure there is no profanity being used and rude language
