I have a car seat in mine, forward facing now, was an infant rear facing. There is plenty of room in there, and like FXNGLAS said, there is an anchor on both left and right sides for the car seat. No special seat needed, just a good quality seat will do fine.
By the way, please don't put the little one in the front, even if you turn off the air bag.

Oh, and CONGRATULATIONS!!!
