Since the stool test
is normal i guess there is no infection in stool.Now to the basic question How many times does your baby pass stools in a day? Every child who is on breast feed or is around the age of your baby passes stools as many times as he feeds it is normal for him.If the stools are loose and the baby is not crying during stools or is not uncomfortable and does not look dehydrated even that can be normal .If your baby does not look dehydrated then please don't worry ;give him water enough to hydrate him.If you want to give medicine for loose motion
give him syrup-NUTROLIN-B it is formuation of vitamins
with a healthy bacillus .It will control motions .
