So my 4 1/2 month old has been on breast milk from day 1 and enfamil gentlease since 3 months. Long story short, we both had thrush and I wasn’t producing enough for her appetite so I’ve been giving her both. I know green is normal for formula fed babies. Hers is like green with the yellow seeds from breast milk and today it has a Greyish tint? Just want to know if this is normal before I go running to the ped.
