Best bottle brand for mix (BF & FM)

Hi mommies ask lang kung ano suggestion niyo na bottle brand na swak para kay lo. Pure Breastfeed po kasi sya kaso need ko na sya sanayin sa bottle since next year balik na ko sa work. Patapos na ML ko.Actually we're trying now, kaso ayaw nya iyak sya ng iyak due to nipple cunfusion ?? Nasa photo yung recent bottle na pinapagamit ko sakanya. I hope someone could help me. Thanks in advance! ??? By the way, my Lo is 2mos and 13days??
