Re: Oversupply, allergy, or something else?
Welcome to the forum!
There are 2 other potential cause for green poops: first, that the green poop is a variation of normal, and second, illness. Babies with a tummy bug often poop green for a while.
The most likely explanation for green poops in a young baby is oversupply. Most new moms have a lot of milk, and you can have more than your baby needs even without feeling engorged. The fact that your baby is gaining weight pretty quickly and is gassy points to high supply.
If it's not oversupply, and it's not an illness, then allergy/intolerance to something you're eating may be the explanation. Dairy is the most common problem- and keep in mind that when a baby h a problem with cow's milk, it's not lactose (sugar) intolerance, but rather an intolerance of the proteins in cow's milk. So you might want to consider trying a dairy elimination and seeing if things improve. Simply cutting down on your intake may be enough, but sometimes things don't improve until mom has completely eliminated dairy, including trace amounts found in processed foods, for several weeks.
The good news is that green poops are not in and of themselves a health problem. So don't let them worry you too much.
