DS is turning 4 in a couple of months. For context, his nursery teachers have suggested he may have some ADHD/Autism traits. He loves any kind of vehicle, is obsessed with anything with wheels. He has a balance bike and a scooter and loves them so for his birthday we had planned to get him his first proper bike.
Unfortunately, he has become really resistant to wearing a helmet over the past few months. He will ask to go on his scooter but as soon as I put his helmet on him, or even near him, he gets really distressed and refuses to wear it. He cries and lashes out and seems genuinely scared. When we ask why he doesn't want to wear a helmet he says it "hurts" him but we're certain it isn't too tight or anything so not sure how this can be the case. We've asked where it hurts and he indicates under his chin where the strap goes but even if we loosen this he still gets very upset and claims it hurts.
DH bought him a helmet with his favourite TV character on thinking that might help, he got excited when he first saw it but when DH tried to put it on him he went ballistic. He desperately wants to ride a "big boys bike" and we've explained that he cannot do this unless he wears a helmet but he is still adamant he can't wear one.
Has anyone else had this problem and how did you get past it? I just can't see how he's ever going to learn to ride a bike and feel sad for him that he's going to miss out.
