I scrolled down to try to find the post but it must be waaay down there because I couldn't figure it out.
I wanted to suggest a solution to hiding/storing meds.
I bought this cabinet from ikeahttp://www.ikea.com/ca/en/catalog/products/24586510/
to store the bathroom cleaners so the kids couldn't get into them. It's made of metal and shallow enough that put up high on the wall, it's not that obvious.
In fact, in my little home, my little bathroom, I placed it so that the lock is on the bottom. Only fits 3 cleaning items but I am a simple cleaner so it suits my needs (a yoghurt container of baking soda to scour the tub, a jug of toilet cleaner and a lysol spray to decontaminate the outside of the toilet. easy, simple)
I don't lock it, btw, because it's up near the ceiling. Even on a chair, the kids would have a tough time reaching it and once tall enough to do so, they'll be old enough to handle the stuff responsibly and hopefully cleaning the bathroom too (a mom can dream)
