When my kids were little I made juice from frozen concentrate. I always added quite a bit more water than it called for, figuring water was better for them than juice. When they finally tasted *real* juice, they realized I had been holding out on them! ;)
My Mom did that with my scotch as a kid, it took me years to forgive.
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.
