If you are trying to convince her to go be with her mom then I bet her mom is a good person and someone that can help her. She would also probabaly be more able to help her long term since her kids are grown and you are probably very busy with 3 little kids. You are only on day 2. This is going to be so hard for you. She needs a long term plan and no social services here will compare to what her mom can be to her at home. You also need to think about what is best for the baby as your primary thought when helping her. Living in an apartment, no help with the baby, working to barely pay the rent, trouble caring for the baby VS being with her mom where she can work and have her mom's help w/ baby. You know what you need to do here. Good Luck.
