We did this from 12 months until 21 months or so. At around that age she was big enough to be comfortable in the trailer with the helmet and without the Boppy.
Additionally, a quality helmet will help. We bought her a Trek Lil' Dipper (in pink, natch) and she loves it. She also uses it on her Stryder bike without a problem.
We went and bought skateboard style helmets because they didn't stick back behind the head as far as a bicycle helmet, the LBS had them and recommended them, seems they were aware of the issue already.
