0 to 6 monthssss.

Honestly anak, both are okay naman pero it really depends sa baby mo, bonna is more affordable pero maraming moms sa circle ko ang nag-swear by Nestogen kasi mas gentle sa sensitive tummies at may probiotics na okay for digestion, so mas konti ang colic complaints hehe! Best thing talaga is to observe kung paano mag-respond ang baby mo sa formula, kung okay ang poop at walang excessive gas, then that's the one na okay para sa kanya. Pero kung may doubts ka pa rin, check with your pedia na lang to be sure, especially kung first time baby mo or may sensitive stomach siya!
