thats the reason i passed on the trailer, storage, theft and urban commute. to me they also seem like a mini parachute that on a windy day would suck azz.

what i did on friday was wife drops him off at daycare/school and leaves the topeak seat with him. so the commute portion to the school was lighter and quieter.
you could try the same with your trailer if the school wont mind?

oh and for comparison purposes my kid is only 30#'s so he has awhile before he will hit the recommended limit.

I am hoping by the weight limit i can get one of the trailer bikes where he can help pedal.
