My boy has been on friso gold 1 since week 2.. now he is week 5. Same like you, I fed him with formula of max 2/3 feeds a day, while the rest are breastmilk. My son has his acne since week 2, starting from his head, gradually gotten better but those spots went downwards to his face and thereafter his neck and upper body. Doctor says those are heaty rashes and will gradually go away. His poop had been once or twice a day, yellowish mustard.
