Babes on bikes

I am beginning to research how to take little Anna bike riding. Of course, I'll leave the decision about when she's strong enough (head and neck strength, mainly) up to the doctor, but I need to get started on researching what to buy.

This lady took her child around in a trailer and simply attached the baby seat inside.

This place, the Bike Helmet Safety Institute, recommends (and I've read this other places) not to take baby along on any bike rides until she's at least one year old. In fact, some states prohibit kids under 1 year riding on bikes or in bike trailers.

This guy has a page that addresses trailers vs. kiddie bike seats.
