A.M.
I started giving DD water at 6 months during the serving of her baby food. I do not give juice and probably won't for several years. I just dont see it is necessary and it has o much sugar. My Dr did suggest at 7 months or so to start changing the method of delivery for fomula/water. I.E. start giving formula in sippys and water in bottles occasionally to set the expectation that formaula doesn't always come in a bottle. Good luck
