Aww, don't worry mama, maraming babies ang tumatagal before they get used sa bottle! A few of us tried introducing the bottle around 4-5 months kasi, at ang trick talaga is consistency, offer it habang hindi pa gutom gutom, maybe midday feed, and let your partner or trusted helper give it first kasi minsan ayaw nila if lasa mo sila. Patience lang talaga, some babies need weeks bago ma-adjust, but your 6-month-old will get there, I promise!
