Hello and welcome to TE!
I'm a new rider (coming up to two years now) and have a trailer for my four year old. It doesn't get used that often at the moment, as I'm using the bike more for solo "me" time, and also because the traffic on the nursery run is pretty unpleasant and unpredictable and it's just no fun. That said, we have fuel-delivery drivers strike looming so I expect I'll be back dodging the lorries again soon. I'm hoping that we'll use it again when she starts school in the autumn, other than that I use it to take her to her favourite park in town and we always hire one on holiday. Here's my trailer thread http://forums.teamestrogen.com/showthread.php?t=41526
