Hi ! For my baby, also drink "心美力" in the hospital, but after home, I haven't got this so I drink nestle ...But, no 便便 within two days, then I change back to "心美力", also,我一轉就轉, I have consulted from my cousin - she is a nurse. Finally, no problem at all. Don't worry. My baby also 便便黃色一"pet pet"ga. It's fine .
