restricting search options on YouTube so is child-friendly

[ILiketoMarmiteMarmite]

I've looked all round the settings, account profile and all that and I can't find a way of restricting words, etc from coming up - you know, like SafeMode or whatever it's called on Google. I searched for the Mom Song this morning & got a lot of very "mom"-related offerings as suggestions for my search box.

Any ideas?
