When I worked at the chemist (many moons ago) we were always reluctant to give out Immodium. The runs is your body's way of clearing the bug out. If it lasts longer than 24 hrs or you become much worse, then go see a dr. If you trap the bug in your system by stopping the diarrhoea you run the risk of causing an infection. Having personally had a bad stomach/gut infection once before (although not from using Immodium), I wouldn't recommend it!

Make sure you drink plenty of water and maybe have the pawpaw ointment at hand for sore bottoms. Also, those wet toilet wipes, or wetting the toilet paper before wiping, can help ease that discomfort. Wiping with some pawpaw ointment on the toilet paper itself also works.

Sorry the household is not feeling well.
