I watered down my son’s juice as well.
When he was a little guy he LOVED the stuff. I think “juice” was his first word. LOL!
Anyway, I got to the point of watering down the juice to half juice/half water. His doctor recommended it because his weight was starting to creep up.
After a few months his weight leveled off and has remained normal into his 20’s.
When he had his first taste of “real” juice at him grandma’s house he was shocked. It is pretty sweet if you are not used to it.
LOL yes, that’s what my kids said. I also did not feed them much sugar either. To this day they are not sweet eaters. I mean they will eat some, but they don’t consume mass quantities.
