I have not been in this position before, my husbands only kids are with me. However, my husband is a step-father to my son which is VERY difficult sometimes.
Anyway, how can bio-mom just "decide" she doesn't want her daughter anymore? and that she has to go to you full-time??? Can you and husband just refuse to take her? Your husband, her dad, wouldn't even be home to take care of her and you have enough to deal with. How can anyone say it's in difficult child's best interest, which is what all involved should be concerned with?
If it's your husband that wants to take her, try to reason with him that this is NOT what's best for your family or difficult child and he wouldn't be home anyway. Everyone in your household needs to be considered, who cares what bio-mom wants???
