Aw yan ang hirap talaga, pero don't worry, maraming mums na successfully nag-transition! A few of us started by introducing the bottle when baby was around 3-4 weeks, doing it midday kapag baby least hungry para less frustrated, then eventually replaced one feed at a time so your supply adjusts pa rin. My advice: let someone else (partner, lola, whoever) give the bottle habang ikaw away, babies sometimes reject it kung nakita nila kayo, haha, kaya mas madali pag ikaw absent, at least that's what happened sa circle ko! Just keep expressing or pumping para hindi mababawi ang supply, lalo na ngayon lang you're transitioning.
