Ay ganyan talaga, mama, sometimes kapag lumipat ng milk kahit parang pareho lang, affected ang tummy eh, kaya normal lang kung may adjustment period siya! A few of us tried mixing the old milk with the new one gradually para hindi ganitong shocking sa sistema, at nakatulong talaga, so maybe try na yan first bago mag-full switch? If she's been okay with Nestogen, pwede mo ring i-continue pa lang talaga dahil hindi naman kailangan magbago if it's working, pero kung gusto mo talagang mag-explore, ang iba sa circle ko prefer ng Enfagrow or S-26 Gold para sa toddlers, mas mura lang ulit at okay din. Just observe kung paano sya mag-adjust sa next week or two, basta sigurado lang na umiinom sya ng enough formula plus solid foods, kaya niya yan!
