I live in PA also and all of my actual placements have been infants. Truthfully, when I started fostering I wanted ages 3-8!
My first placement was for a 2 m/o preemie. 15 months later and I still have her
My second placement was for a 4 m/o girl. And my third placement was 9 m/o when she came.
I do respite and have had different ages, but I really enjoy the babies.
