I would take her if I had room, but would let her know that like she expects part time care, you also will expect that she would understand because of that, her child will be kept contingent. If a full timer comes along she will be bumped. The way I see it is (as long as its a good kid and good family) you benefit because thats money you wouldnt have otherwise. just make sure you agree that it is temp. for the both of you.
