Wa'alaikumassalam! Ah, boleh je nak teruskan breastfeeding first child sambil pregnant dengan baby ke-2, memang ramai mums yang buat gitu. Yang penting, pastikan you makan cukup-cukup dan minum banyak air, sebab your body kena provide untuk dua orang sekaligus, and it can be exhausting. A few of my mum friends said nipples can jadi more sensitive during pregnancy while nursing, so be prepared for that, but check with your doc or lactation consultant just to make sure everything OK with your pregnancy, especially kalau ada contractions or anything yang worry you. You're doing great managing both!
