Sorry but this is such a bugbear whenever I see it - a child on the back of their parent’s bike rightly wearing a helmet but the parent cycling isn’t. What if there is an accident, yes the child will be safe but their parent is risking their child seeing them with head injuries or worse. Please, please, please, from an ex-A&E nurse, wear a cycling helmet (cycling with a child or not)! No one thinks it will happen to them until it happens to them. Looking after your child means looking after yourself too!!
