How old is your daughter now? I think we started my daughter on the tagalong when she was an old 3 (as in she was about to turn 4 that fall). She could barely touch the pedals, but she could balance and hold on alright.

We started with short rides, 2-3 miles and built up from there. Last summer we took her on a couple 15-18 mile rides on the tagalong, she was 5 years old. Although, she did nod off at the end of the 18 mile ride--somehow she managed to hang on while asleep. This summer we have plans for 30 mile rides.

It's an adjustment riding with the tagalong. You can definitely feel them moving about and you'll find yourself yelling at them to stay still! Or Don't lean to the side! But, you'll get the hang of it. You'll also have to take wider turns and stopping will is more of a challenge. You'll want to slow down earlier as you are towing that extra weight--it can be like trying to stop a freight train.
