Child seat to accommodate bike?

Hi, everyone. We are doing things a little backwards here: We have not yet purchased neither a bike nor a child seat for a bike, but we know we want both. I've read that child seats can be pretty specific to the style of bike that you own and thus don't want to buy a bike that doesn't work well with a child seat or vice versa.

Does anyone have recommendations on a bike (preferably a road bike) that well accommodates a child seat? And then, a child seat that would work well with that particular bike? I hope I'm not asking for too much here. Thanks for any help!
