Needing 40 dollars for my grandsons needs

I am completely broke due to rent and bills . I have no money for gas but what I really need is money for my grandsons diapers,wipes, milk, and food. He’s adopted because my daughter couldn’t take care of him so I am helping raise him along with my 3 kids and it’s allot on me but I am dedicated. This had been my hardest month on us due to unexpected bills. Please can anyone help us out?
