Uy, honestly ang pinaka-importante is finding something na comfortable sa baby's latch at hindi masyadong hassle to clean, a few of us nag-try ng different brands kaya may trial and error talaga! Some babies prefer wide-neck bottles kasi mas natural ang latch, parang breast feeding, while others okay lang sa kahit anong shape, so basta okay sa inyo both, that's the one na! I personally love bottles na may anti-colic features para walang air bubbles, at check mo kung compatible sa sterilizer mo para convenient, sis, one of my mom friends swears by the starter sets kasi may kasamang different nipple sizes para sure fit sa baby mo.
