We have a 4 month old son and recently purchased a bike trailer. The trailer has a hammock seat so can take small babies and he sits in it in almost the same position he would in a car seat.
My question is: Should he be wearing a helmet?
My first throught is no as he can only control his own head - I can imagine the extra weight of a helmet causing him neck/back strain. It's up to me or my wife to ride appropriately so that he isn't going to be rattled around.
What have you done? What do you think?
