I agree with Jadis with regards to the constipation. . .but it's pretty rare for a bf fed baby to get constipated. I agree with the other ladies that it's a little too early. Introducing foods other than bm (since you're bfing), can cause a host of problems including serious allergies (or so it is thought), and a leaky gut. But here's the real reason he shouldn't have anything besides bm right now. It can actually cause malnutrition. . .I'm sure he didn't give him enough to cause problems.

So I don't mean to scare you. But bm is the food and nutrition that your baby needs and putting water or juice or anything else in his belly will take up the space he needs for good nutrition.
With that said, we don't do juice until after they can hold a cup on their own or juice box on their own because of the high sugar content.
