The bikes are pre-assembled by a machine that overtightens the rear axle.  I had the same problem with my daugher's 12 inch huffy princess bike and my other duaghter's 16 inch Schwinn bike.  If you loosen the nuts on the back axle it fixes the problem.  I have read that the idea thing for these bike is to have them re-assembled and re-lubricated by a bike shop, but I thought this might cost as much as I paid for the bike.

it's kinda tricky to put the bracket on, but it should have come with a weird bracket that kinda looks like a brake caliper, the bracket goes around the back of your frame, as opposed to attaching to the wheel pin like the inStep trailers...if you don't have the bracket, i dont know what you can do

Loosen up the hub nuts. Center the wheel between brake pads. Put something like a screw driver in the space between wheel and frame to keep the wheel centered and not moving as you tighten the nuts.
