Do we stay, do we go, do we dual enroll

Well Art and I went to the Child and Family Services Foster Program Orientation.  What did we learn?  The government wastes a lot of money, there is a lot of work to become foster licensed, yes you have to be foster licensed in order to adopt, and there will still be a lengthily waiting period.  We are now officially more confused then ever.  We have been on the list 8 months for domestic infant adoption and only have had more couples added to the pool and no babies/no calls for babies.  If we were to adopt an infant I believe in the future we would adopt an older sibling set where if we straight adopt a sibling set with a infant or toddler in the sibling set then we would have our instant family.  But with adopting from foster is it an instant family?  

The children may need behavioral counseling, they may resent us, they may hate us, they may ???????  There are so many questions.  So we turned in our interest form and we will go from there.  I know the domestic infant counselors want us to wait one year before changing programs but I feel like if we adopt from foster that we will be making a difference, something that Art and I do through volunteering with children now.  I don't want to look at my kids though as a service project, I don't think that will be an issue but what if?  An infant will always be able to find a home.  I can honestly say I have no idea what I am feeling.  Am I just impatient?  Am I meant to love a sibling set?  Am I suppose to dual enroll and see what happens?
