I have long-term families (12 yrs, 10 yrs, 8 yrs, etc.), so we discuss the kids' well being just like I would if I were talking to my sister about her kids. A mom might say, "Joey just isn't a water drinker! Can you help him to remember to drink?" And I would fully know that they are doing the same at home. You've heard about that "village"? I live there. 
Again, I wasn't criticizing the OP or you. And I'm not trying to change anybody's mind here. Just sayin' ....... 
(Sorry, OP. I didn't mean to hijack your post!)
I have heard the it takes a village and I think your both villagers, just doing things differently and that is ok. Both parties are making sure needs are met. One leaves water out, one doesn't. Whatever works best is what I go for.
