I've just straightened the rear wheel on the bike of a friend of my daughter and while I was at it checked over the rest of the bike. This leads to my top tip for parents of children who cycle (which IMO should be every parent of an able bodied child).
Before you start worrying about whether your child is or is not wearing a helmet1 make sure that the brakes on their bike work. Not just when the bike is new but regularly.
