Hey Skye, I know what your dealing with. I worry too that my kids have too much. I sometimes water it down, and I only give it now 3 times a day, morning, before day sleep and before bed. I guess though as long as they aren't filling up on it and not eating anything else they should be fine. They love their water as well though, so I guess I'm not worried about that. Hopefully it will just mean they will have lovely strong bones
