Incident This morning sparked a debate with my dh. my ds is in year 2 (so 6/7 years old). His class mate Road into the play ground on his bmx, pulled a skid, clipping my pram in the process and went over the handle bars. Narrowly missing the corner of the wall. His mum was no where to be found so I dusted him off and told the teacher what happened. His mother arrived about 5 min after incident and was told by teacher that riding a bike on school grounds is prohibited by the school. mother then says " you have to tell him because he won't Listen to me". Am I being unreasonable in thinking that helmets for any age sound be compulsory? Dh brought up making it compulsory enhances nanny state measures and I compared it to wearing a seat belt. Aibu?
