Ay mama, nakakagalit talaga yan at valid yung feelings mo. A few of us in the mum group have been through similar situations with family not stepping up, and honestly ang hirap ng ganitong position lalo na pag first time mom ka pa lang at may baby na ng kailangan. Have you tried reaching out to local government units or barangay offices? Sometimes they have assistance programs para sa moms na struggling with baby essentials like formula at diapers, at may tulong din para sa documents. I know it's frustrating na dapat sila ang sumusuporta pero at least may options pa rin tayo, kaya don't lose hope mama, you're doing your best for your baby and that's what matters.
