When I was at my 6-week post-partum check-up, I picked up a free sample of Enfamil's DHA supplements. Very clever of Enfamil! Now they can tap into BOTH markets! I was wondering if anyone else is taking a DHA supplement, and whether it's necessary for someone like me who doesn't eat a lot of fish. Also, any idea where I would pick it up at the store? With the Enfamil formula, or with the vitamins and supplements?
