I just have the dye-free Motrin, as well, but actually bought it for DD.
I'm sort of the frame of mind to be generally prepared (like have a thermometer and some Motrin) but if anything else goes awry, then I just go to the store and get what I need.
In DD's first year, she seemed to always get sick. I bought lots of teas that I drank to give her a boost through the breast milk and also some herbal children's immune-booster type things. Now I give her vitamins and occasional supplements to help keep her healthy (not sure what I'm doing right, but it's working! In the last year she's maybe had the sniffles twice-- that's IT. The first year of life she had a cold every other week it felt like!) Okay, I'm getting OT, but the point being, I just get what I need when I need it so I'm not stocking a billion things around the home.
