Earlier this week, we started transitioning LO from breast milk to formula. About a month and a half ago, we already had been supplementing his bedtime feeding with one formula bottle. His other 4 bottles were expressed breast milk. Then about 3 weeks ago, we started supplementing another bottle with formula.

This week was his first few days of all formula. His poops have been dark green and watery for the most part. Last night, it was a little more solid, but my caretaker sent me a picture of his poop today, and it's dark green and watery again. Anyone else experience this? What did your LO's poops look like during the transition? Just wondering if I should call the doc to see if he's allergic to the formula. We're using Enfamil Gentlease.
