This pin has someone putting a timeline on the side of the medicine bottle with a sharpie, that way you can mark off when you have given the medication.This person is genius, why have I never thought of this. Of all the antibiotics I have given the kids and something like this did not occur to me !! I did this with our last round of antibiotics, this time for strep throat, and it was a life saver. I was able to see when I gave the antibiotic and if I had missed one and needed to make it up. Thank you to the smart person who came up with this, this is why I love Pinterest.
