My Ds has always worn a helmet , he's 7 now and rides really well so now rides to school with Dp (his dad) .
The bikes are kept in PIL garage a few doors down from us as we don't have room at our house , all our nieces & nephews are in and out regularly and ds helmet couldn't be found this morning .
I've told Dp he either needs to find the helmet or we need to buy a new one if Ds is going to continue to ride his bike but he thinks I'm over reacting & says that plenty of children ride without them .
Am I over reacting ?
