I think the hard part of your story Little, Is most Birthparents feel like they have no other choice but to place there child in a home where they can be provided for, financially and emotionally. You then come along and say that you were offered enough money to parent your child, but still chose to place him/her. For those of us that wish someone would have "helped" us parent our children we placed, it is hard to understand! I realize that your belief is that God has given you a child to place with another family, but I believe that God has given you the resources to parent, it is just in how you wanna see it.
Sometimes when we pray for answers and we dont get the answer we like we tend to think he hasnt answered it yet...Know what I mean. So who is to say that your uncle was sent from God to offer the money to you so that your children could grow up as siblings together with there mom??? My bible and my God believe that if all possible families should be together
But again, Good Luck to you
