Dont worry about the extra amount of enterogermina
You must assess if the breast milk is adequate. It can be done by expressing the milk in a calibrated glass every 2nd hourly. If the amount is anywhere between 30-35 ml, it is fine.
Inadequacy of breast feeds can lead to decreased urine output. Diarrheal episodes in a child can also lead to decreased urine output.
You can get a stool test
done to rule out any infection.
You need not discontinue enterogermina after a single dose.
