Hello doctor,

My baby is 4 weeks old. I fed her a combination of breast milk and formula milk. I changed her formula to enfalac from friscolac slowly, and started solely on enfalac yesterday afternoon. I changed the milk (upon consulting with the pediatric clinic) because she was having constipation and gassy stomach. My baby had watery stool once yesterday and today (only after being completely on enfalac). She also is quite gassy (most days than not) and gets upset with it (cries last about 10 minutes). My worry is that if she is okay and, does the enfalac formula milk agree with her or she struggling with something else. I had to add formula milk due to insufficient supply of breast milk.

Welcome to icliniq.com.

Breast milk is definitely best and first choice but as it is insufficient and you need to supplement with formula feeds, all these formula milk are cow's milk. It is not clear from your query- which Enfalac formula you are giving as there are so many different types and also in the powder form and in ready to feed one. Watch it with the same formula milk for next 24 hours, feed more on breast feeding, and keep a watch on urine output. It may settle down slowly. If not then get, stool test - routine analysis, give Pedialyte - 15- 20 ml after each loose motion (give as small small sips), and better to give a milk formula which is HA (hypoallergic) like Similac or Nan or any other.
