Ive looked at thre trailers. I just like the seat more because its more of spending time with the kid than shoving him in a little trailer. I come from a family that was raised by nuns and a single mom in the 70s, so I feel that kids are resliant. Todays parents are too safe, if you never let your kid touch the hot stove how will they know not to type thinking. But vaild points to all. Maybe wait till i can get him on a tandem type trailer
