Low potassium levels, also called hypokalemia, can affect people of all ages. Sometimes the condition is the result of a temporary condition--for example, if you perspire a lot during sports or intense exercise and you don't replace the water you've lost.
Diarrhea in infants. Children who have diarrhea may have less energy, dry eyes, or a dry, sticky mouth. They may also not wet their diaper as often as usual. Give your child fluids for the first 4 to 6 hours. At first, try 1 ounce (2 tablespoons) of fluid every 30 to 60 minutes. If you are nursing, keep breastfeeding your infant. If you are using formula, use it at half strength for 2 to 3 feedings after the diarrhea starts. Then begin regular formula feedings again.
Too much fibre for a toddler could give her diarrhoea. Give your child plenty of fluids to help moisten her poo. Water is best, although you can offer well-diluted fruit juice too (at least one part juice to 10 parts water). Donât give your child fizzy or sugary drinks. Constipation may make your toddler sluggish and low in energy. But being active will help to ease her constipation.
