You can buy special "baby photo posing tables"; I'm not sure if that is what Kim is using but you can find them at on-line photo supply stores. They also sell cute little chairs with seatbelts in all different styles, fun blankets, etc.

You can also use beanbags covered with a nice blanket or fur cloth.
One photograph I know used to have the parents bring in the child's car seat. He would then drape a 6x6 foot pretty cloth over it all, hiding the edges and buckles and etc, and place the baby back in. Then he elevated the back of the carseat with some books to make it tilt forward for better light, then would take pics.
Other people sometimes have seamstresses make a cute cloth cover for a bumbo and sit older kids in that.
I like many of these idea but haven't tried them, although they sound fun. I would love to hear more ideas from kim & others on how you pose babies!
