How long was baby fussy with formula change?
Weve introduced hipp organic to our baby as he is currently on aptamil pepti 1 but we don't think he has cmpa.
Weve done it slowly with 1oz for a day then 2oz for a day were on day 2 and hes extremely uncomfortable, being sick more and crying and writhing a lot. I know it takes a while for them to adjust to new formula but does anyone have any experience? How long should increased fussiness last?
