Mom to Foster Children

Hi, I am a mother to four wonderful children. Two of which I gave birth to and one we have adopted the other one just came to live with us in foster care. I came across Y!A a while ago and found the adoption page...got into it so that I could learn from everyone. Now that I am here, I have a different perspective on adoption / the children / the mothers and fathers. I learn every day and sometimes cry from the stories that I have heard - but it makes me a stronger person knowing how others feel. We live in the Midwest and have only done foster / reunification. We have sent two children home (parents worked their asses off to get them back :) We are adopting again - my newest son just came to live with us - he is 9 Is it worth it? Most day's when thinking about it - yes and no! Everyday that I see them - yes!
