Get one or two of those plastic dosage counters for 7 days. If you take them several times a day, buy one for each time and mark them which time of day it is for and put them in an obvious place so you don't forget them. Put the others behind lock and key. Get a small metal box with a lock or put a lock on your medicine cabinet. That way, you have what you need out for the entire week, it'll be obvious if any are missing, and the others are in a safe place where the kids can't get them even if they ever wanted to...and you only have to refill the container once a week.
