Aww mama, ganyan talaga pag may tummy issues, ang pagbabago ng milk sometimes talaga ang sagot! Since okay na ang poops niya with NAN AL 110, I'd honestly stick with it muna for now, lalo na't nag-improve siya after the switch. A few of us sa mommy group namin noticed na hindi lahat ng babies agree sa same formula, kaya once nakita mo na ang improvement, mas safe na mag-stay pa lang doon habang tumatagal. Maybe check with your pedia kung kailan okay na mag-transition back kung gusto mo talaga, pero since NAN Al is working for her tummy, there's no rush, baby's comfort first!
