Coconut milk is higher in natural oils, so look out for signs of spoilage early. You can usually determine if this milk substitute has gone bad by smelling it and even tasting it a bit.

I would do formula at that age as well. Coconut milk is great as a food but can act as a laxative so that much per day could definitely have some GI effects. Coconut milk is also low in calcium, cholesterol, protein, and most vitamins compared to both breast milk and formula. Mom to Taiga born 6/2010.
