I don't remember it all that well but my family did fostering when I was young. I think that was because one of my parents was home then so they stopped when they were both in full time work. I'm pretty sure we just did emergency care so we would only have a child for a few days- and they were always young toddlers like us so I remember playing with them and just thinking we had another friend for a few nights sleepover.

I'd like to do the same thing but sometimes I worry about being overburdened and not being able to cope... will wait till we're settled with baby#2 then look into myself I think.
