I think it very much depends on whether your LO takes to the taste of it. Generally such drinks are packed with all the "good stuff" so drinking it as a supplement to a well balanced diet should be good. We, as adults, know that so we drink it. However for kids, they drink it because they like the taste. I don't about your LO but my boy does not like the taste of such beverages (although it is sweet). He only likes his milk.
