Advice

So I’m currently pregnant and my other kids father wants to sign his rights over so my fiancé can adopt them and he wants a reduction in child support. He wants me to do my part of the paper work and file them before the end of the month.... I really don’t want to deal with all of this before having my baby. I guess what I’m asking is what would everyone else do knowing that the court isn’t going to change anything until the kids can be legally adopted?
