Yes, this is possible if the child hasn't been adopted. or the mother could destroy everything the child has known and regain custody after they are adopted. This would be a very wrong act and it is not recommended.
lost the child to whom?
The adopted child have the same right as the biological child.

No she doesn't.
Marriage by itself does not bring custody rights to non-biological children. Where the children go when the biological mother dies depends on who has custody, whether the non-biological father has adopted the child, whether the biological father wants the child, and on the laws of the state where all of this is happening.
A birthfather is the biological father of an adopted child, or a person's biological father.
Hitler had no children, biological or adopted ones.
If the child is in foster care you pay but not if the child is adopted. Then the child have new parents who are responsible for him/her.

An adopted minor child has the same equal rights to financial support by the parents as does a biological child.
