How many ounces of fluid does my toddler need in summer?

My son is an active 17 months. I am really worried about dehydration at this time of the year. I know that toddlers don’t eat as much as infants do. But how do I determine whether or not he is getting enough fluids and food.

The caloric needs of the healthy toddler are considerably lower than those of the infant, who normally triples his birthweight by one year of age. A healthy child can be expected to gain 3-5 pounds during the entire second year.

The healthy toddler (once the infant willing to eat everything that came his way and lots of it) now eats less and seems pickier about what he eats. His caloric needs are about 1,000 calories per day, and he should have plenty of opportunities to choose healthy foods from the four major food groups. Avoid foods like whole grapes, raw carrots and nuts that are choking hazards, and avoid “eating on the run,” also a choking hazard. Limit his intake of juice to 4-6 ounces per day and whole milk to 20-24 ounces per day; offer plenty of water to drink, especially on hot days. The toddler should be drinking fluids from a cup.

To avoid dehydration (and sunburn), limit outdoor activities on hot sunny days – especially during the hours from 10 a.m.-3 p.m. – have plenty of cool liquids on hand to drink, and use sunscreen, hats, and appropriate clothing. Colorful water bottles and sipper cups can be a real hit with some young children.
