Aw mama, totally get it, ang pagod talaga pag walang tulog at kailangan mo pang mag-work, kaya mo yan! A few of us nag-transition around that time too, at honestly ang key is patience lang, plus maybe start with expressed milk in the bottle so familiar pa rin ang lasa para sa baby habang nag-adjust sya sa bottle. Try letting your partner or family member give the bottle habang ikaw nandoon pa lang pero hindi visible, para slowly mag-adapt si lo; also, consistent timing helps, same time every day ang bottle feeding so routine na lang eventually, at madidivide na rin ang work load mo para makabawi ka ng tulog nang slight.
