When our children was in the single digits DH bought a 4 wheeler for them, and yes they enjoyed it. While DH and I switched holding a rope behind them.
Well, this year DH got them this. Before this, he actually wanted to get them a tiny motorcycle. I said no, plus at that time toy fund was none existence.
There is something wrong with the breaking system and we don't let the children drive it alone. At above picture, DH was riding behind until we fix the problem.
