Can you give a 2 year old imodium for kids?

I wouldn't: Diarrhea in infants & toddlers is best managed with proper fluids and natural plugs, like applesauce/bananas and rice cereal. I have never needed to use meds on kids that young.

Yes: Yes. The Immodium box may not provide dosing information, so here it is: For a 2-year-old weighing 28.6 to 44 lbs (13 to 20 kg), give 1 mg of Imodium 3 times a day for the first 24 hours. After that, the dose should be 0.1 mg for every 2.2 lb (or 1 kg) after each loose stool - up to a maximum 3 mg per day. If diarrhea does not get better in the first 48 hours, talk to your family doctor.
