Ay hirap talaga yan, mama! A few of us tried switching to mixed feeding around that time, and honestly, mas okay siya kahit medyo adjustment period muna. Since baby is already used to your nipple, you might want to try bottles with a slower flow or ones designed para hindi ma-confuse, a lot of moms sa circle ko swear by Philips Avent or Tommee Tippee, pero try mo rin mag-research ng anti-colic bottles kasi may kaibahan talaga depending sa baby. For formula, pwede mo subukan ang similar ones like S-26, Enfamil, or Lactogen (kasi familiar na yung taste if nag-breastfeed siya), pero buti kung makaka-consult ka ng pedia para sa best match para sa baby mo. Besides bottles and container, kailangan mo ng sterilizer (electric or stovetop), bottle brush para sa cleaning, at powder dispenser kung convenient para sayo, plus maybe a bottle warmer para sa gabi kasi mas convenient than heating on stove, pero honestly, room temp formula works din, marami na kaming kaibigan na ganyan
