Hey! S26 Gold is a good choice, a few of us moms use it din and our babies did well sa transition, though every baby is different talaga. When you switch, try mixing it gradually with the old milk para hindi ma-upset ang tummy niya, and observe how baby reacts sa first few days (some babies get a bit constipated or may loose stool). If baby has any unusual reactions or you're unsure about the change, best to check with your pedia para sure, pero S26 Gold ay trusted brand naman dito! Goodluck sa switch!
