Good news for parents with kids with vomiting and diarrhea. As we all know products like Pedialyte are very expensive and actually have expiry dates that make us feel guilty if we have them on hand. A study done in India randomly divided 61 kids into either getting Gatorade or a commercial pediatric electrolyte solution. The results? No differences.
I'd be recommending 3/4 strength gatorade any way you can get it into your kid. Remember, chugging may well lead to vomiting so a tablespoon every 5 minutes or in the form of a popsicle are probably the better ways to go.
