I have seen orange milk in the first month of lactation (some has looked like concentrate orange juice) Some decernable causes were large intake of carrot juice, yellow squash, other sources of high carotene, orange gatoraide & artificially colored drinks. For many women this orange color represents only a high level of beta carotene as it does in the colostral phase. Mom may be concerned that her milk doesn't look like the rich creamy @#%$ in bottles. She should be told that her milk is very rich because her baby is very young and that some of the yellow-orange will gradually fade as her baby ages. Is her baby gaining in leaps and bounds? I was surprized to hear that some of you have seen orange milk from B vitamins. In my experience we get calls about green tinted milk from moms who use B complex vits. Years ago, when I first saw this phenomeon Dr. Wade gently reminded me of the basic primer on primary colors I learned in kindergarten: *Breastmilk has a blue tint, B vitamins have a yellow tint. And what do yellow and blue make, Marie?* Green. Marie Davis
