Try the Salvation Army. They usually have food hampers to help out families when they are in need, They also usually have a secret Santa program of some sort to help out with presents for families.
You could also try the churches. If food is you primary concern right now make use of you local food bank.

Yes, there r places that can help u, try ur local Catholic Family Charities or other church organizations. If u choose to get temporary custody of the children it is best and to their and ur advantage to do so, go to the nearest State Welfare Dept.’s Children and Family Services Division, these children need a stable environment and if u r willing to provide that for them the state will help u with more for the children because they will then be wards of the state under ur protection and guidance and they will be obligated to support them with more financial help, food stamps, clothing, Medical and any other special need they might have like counseling etc. It’s hard but u need to do what u have to do for their sake. God Bless.

If your income is modest enough it would seem that adding people to your household may make you eligible for food stamps.

Depending on their age and legal status (such as whether they are in the custody of the state), there is also the chance they could apply for something like food stamps as a “household of one”.
