DH's parents got my just barely 4 year old an immense fancy train that is huge, loud and very prone to falling off the tracks (especially when his little sister barely touches it) and can only be fixed by adults. He loves it, but we've already broken four of the 8 straight tracks and both DH and I loathe putting the wheels back on the rails. Once a curved track breaks it will be useless. And I will be SO HAPPY when it does break
