Eh mak, kena book awal-awal lah, especially kalau nak govt hospital, I know a few mums who regret tak book early enough! Biasanya around 3 bulan pregnant dah boleh register, tapi tergantung hospital mana, so best call direct ke nearest govt hospital depan rumah ko dan tanya, sebab setiap tempat beda sikit procedure dia. For payment, govt hospitals way more affordable compared private lah, but exact amount tergantung on your income bracket and whether ko ada insurance, so dekat time tu dia akan quote properly. Congrats on your first baby!
