Britney Spears, Sean Preston, and apple juice
Looking up information for this post, I read that juice is fine for children 6 months and older, although some doctors prefer to wait to introduce it until 9+ months. Dr. Sears recommends 4 oz of juice, preferably white grape, diluted with water, while Kellymom also says it should be served in a cup instead of a bottle. You can also read the American Academy of Pediatrics policy here.
As parents trying to make sense of all the information, when did you introduce juice with your own kids, and what kinds did you try?
