Hello,
You mentioned your baby's age is 3 months and 9 days. Only and only breast milk is to be given to babies up to 6 months of age. Observe the following:
1) Only breast milk not even water up to 6 months of age.
2) Please stop giving him biscuit or any other form of solid foods.
3) Complimentary nutrition should begin only at 6th month and not before
4) The green stools are mostly due to the biscuit as it can't be digested by baby
5) If your breast milk is not adequate, you can try formula milk only after consulting your pediatrician
Here are few other causes of green stools in babies. It means baby is getting more fore milk which is watery than hind milk or thicker milk. But it's not anything to be worried, baby adjusts himself slowly. Sometimes green foods in the diet of mother giving breast milk causes green stools in baby which is quite normal no need of worry.
If baby is taking any antibiotics for any infection. If baby has
jaundice, you don't need to worry unless the following signs are seen:
High fever
Baby not accepting feeds
Yellow discoloration of skin
Baby fussy and not playing well
Inactive or sluggish baby and difficulty in breathing
As your baby doesn't have any of the above signs, relax and just stop feeding him biscuit till 6th month.
Take care. Hope I have answered your question. Let me know if I can assist you further.
