Seems to me you get a free babysitter out of this...
Well, perhaps not free considering the girlfriend is financially supporting the mother, but once you iron out the financials surrounding that (which is something that you will HAVE to do if you want to have a continued relationship with this woman and your child) youll likely save thousands a year if the unemployed mother in law is a good grandmother. Then when she decides she doesn't want to babysit the child daily, tell her to start supporting herself or never see the child.
This is all assuming there's real love in this relationship.
