Hey mama! For public hospital delivery, usually kailangan mo ng birth certificate or ID, insurance card if may HMO ka, at any prenatal records mo, best to call the hospital directly kasi may mga documents pa na require ngayon. As for anti-tetanus, I think it's usually given during pregnancy (around second or third trimester) or after delivery, pero honestly ask your OB or the midwife sa hospital para sure, kasi bawat situation may difference! One of my friends nanganak sa government hospital tapos sabi ng nurse nila lahat ng essentials covered na, kaya walang hassle, so don't worry too much, most public hospitals are really helpful pag tanungin mo directly what to bring.
