You sound sweet, OP, but vulnerable and young. And, I say this kindly with care, naive.
Babies need a lot of care, love, attention, and maturity to respond to their needs, being a responsible adult with the ability to havd foresight and know what is best.
Even now you maybe feel ready, or might be in the future, can you truly say how you will cope?.As PP have said, you need to pay rent, buy the baby formula, clothes, diapers, medicine, and anything other necessary things. Without a job or place to live, this will be very hard.
I'm not an American resident so don't know how the welfare system works but I agree with others that you are clearly vulnerable, and you're being looked after well by your mom. She clearly only wants the best for you. ❤️
