Honestly, it really depends on what your tummy can handle kasi bawat mama ay different! Ako, nakakasawa ako sa regular milk so nag-try ako ng lactose-free at almond milk, pero some of my friends swear by fortified cow's milk dahil mas complete ang nutrients para sa baby. I'd say try a few brands and see kung alin ang comfortable sa iyong sistema at hindi ka mabagal or bloated, that matters more than which one is "best" kasi kung hindi mo masyadong iniintay uminom, walang point.
