What is the frequency of stools?
Did you notice this change in frequency and color of stools after formula was started? Because many kids on formula will pass green stools.
Reducing substance in stool indicates Lactose Intolerance
What may be done is- try to put him on Exclusive Breast feeding till he completes 6 months of age- which will be the best for your baby. Get his weight, length, head circumference measured every month. If he is growing well, you need not worry.
If his weight gain is poor and continues to have liquid stool or stool frequency is quite high- then stool tests may be repeated (stool pH and stool for reducing substances). If still things are suggestive of Lactose Intolerance- then he might need Lactose free diet. Soya milk (Isomil) will be use in such babies
At present sporlac
is not needed. Try to put him on exclusive breast feeds till 6 months of age.
When ever you feed him, empty one breast completely before you feed from another breast- as the milk that comes later is rich in fat and will satisfy his appetite. Even after that if he is not satisfied, you may feed him from the other breast too.
Take care of your diet- eat plenty of fruits, veggies, nuts, milk etc so that you will produce adequate milk. After he completes 6 months, you may start weaning him on home made foods.
Hope my answer helps you.
Wish your son good health.
