Helmets are a must! we are picking up our long over due Burley this weekend and I can't wait. My girls are older, almost 3, but I already have them trained to associate helmets with bike rides. They aren't allowed to even sit on their trikes without their helmets on and they always see DH and I straping on ours before we go out for rides. Whenever they see the older kids ride around with bare heads they always ask me where their helmets are.

As for where we plan to go with the trailer, right now the plan is to do one weekend ride together with the trailer on Dh's mountain bike. We will hit the closest rails to trails. I'm tentative about taking the trailer on the street with cars but then I might be overly cautious. I don't even run with the jogging stroller on the road.
