How much water should a 60lb 10 year old child consume daily? we were told at least 64oz, but this seems too much for her to drink. she has eds w/pots

POTS important : The pots diagnosis is important here. Follow the advice of the doc following her for that. It is easy to underdo or overdo water consumption, regardless of the age. Rule of thumb - should be urinating 3-5 times when awake. The urine should be a light yellow color. If it's very dark yellow, you need to drink more, and if it's like water, you can consume less. Rule applies through all 4 seasons.
