How old is your rear-facing child?

[brachy]

I thought this might be interesting for those considering rear-facing. I think it will show that kids can sit happily rear facing until X age. On a previous thread, some posters seemed to think you had to switch your car seat so hopefully this can show people that rear facing can be done for many years.

DS was rear facing until he was about 15 months. I hadn't heard of extended rear facing back then (2007)

I would like any future children to be rear facing until 5/6 if their size allows.
