Hi B., my 8 year old daughter takes 2 meds every day for allergies and asthma. We have them right with her toothbrush in the medicine cabinet and she automatically knows when she brushes her teeth before bed, she takes her pills. It's worked out great for us.
Also, about the chores, we have tried "Chore sticks". I saw it on tv but can't remember what show. You take jumbo popsicle sticks and write a different chore on each stick with a dollar amount for each one (anything from 25 cents to $1 for big tasks) Make a poster and put the sticks in an envelope at the top. Have each child design their very own envelope however they want to attach near the bottom of the poster. The kids pick out a stick, have to do that chore, then stick it in their envelope. At the end of the week, they add up the different amounts and see how much money they made that week. It's worked out pretty well for us so far. If you didn't want to reward with money, you could always put something else on the stick they would look forward to. You could even do "points" and give them a goal to work toward (when you get 5 points, we go to McDonalds, etc.) Hope I helped some! Good luck
