I had forgotten about putting on the toothepaste lid, lol. I got lucky. My boyfriend puts it on & I trained my kids right, lol. It also helps that we brush our teeth in the shower. Leaving the lid off means totally gross no longer tooth paste because it gets all liquidy and stuff. YUCK!
As for putting the toilet paper the right way....as long as they put it on the holder I'm good.
I've got one for you, lol. How about SITTING the toilet paper on the holder instead of through the hole! A friend of ours did that last weekend and boyfriend just about lost it! My kids got blamed until she spoke up, lol.
