Ah puting susu ni memang important bila baby dah kena introduce bottle! Honestly, a few of us prefer the ones yg shape dia lebih natural dan slow-flow, sebab baby won't get confused dengan breastfeeding, yang important adalah puting shape dia tapered dan flexible sikit, bukan too rigid. Try brands like Tommee Tippee, Philips Avent, atau MAM; diorang design specifically untuk mimic actual breast shape so baby can latch properly. Best way is observe your baby la, some babies picky, so mungkin kena try a few jenis before jumpa yang dia comfortable with!
