How About Excessive Hydration?
Fortunately, true overhydration, the kind that causes health issues, is extremely uncommon. Even so, it’s possible (though not typical) for your kid to go overboard to the point of experiencing “water intoxication.”
A severe sodium imbalance in your toddler’s body known as hyponatremia [6] might result from this. Fatigue and nausea may be the first signs of hyponatremia, which can thereafter lead to vomiting, brain edema, seizures, coma, or even death.
Seek immediate medical assistance if you think your child may have overhydrated to the point of hyponatremia.
The more likely problem you’ll have if your toddler continuously drinks from a cup (or, worse, a bottle), is hunger. A stomach slosh-full of liquids is not one that will look forward to dinner.
Have a toddler who never appears to want to eat when it’s time for a meal but who uses a sippy cup as a comfort object? Think about providing non-water beverages less frequently, perhaps only when you serve meals. Perhaps, their appetite will increase.
