My four-year-old hasn't quite kicked the habit of "helping herself" to many of her siblings' possessions while they're at school. Today she "borrowed" my oldest daughter's deodorant--and used it (but at least she used it correctly).
Now before anyone judges me as being a distracted mother, let me fill you in on her strategy--or ability to seize the moment, rather. At lunchtime she spilled a cup of water on herself accidentally. I sent her to change her clothes while I cleaned up the mess and took the wet laundry into the utility room. She's quick--in more ways than one. Somehow while changing her clothes the idea must have dawned on her that deodorant was needed. She sees her teenage sister using it; why not her, right? So she helped herself. . .and hid it in her room for future convenience.
I noticed the scent, but thought she had put on some lotion, which she is allowed to get for herself. . .now that she's learned not to put it on the carpet. After supper, however, when my oldest complained of the missing item, I made the connection and sent the kids on a search. The deodorant was found and returned to its rightful place.
As we headed downstairs for a family night, my second daughter confided to me, "It's okay, Mom. I know where all her hiding places are." Instantly a little head popped around the corner and exclaimed, "Nope. There's still one!"
