What to do Rephrase.
Toddlers respond much better to positive instructions than negative ones.
If he persists, take the sprayer away from him, or take him out of the tub. As young as he is, your toddler desperately wants to feel independent and in control. When he begs for a piece of candy before lunch, sidestep a straight denial by offering him a choice between halved grapes and apple slices. Drive him to distraction. A toddler is hard-pressed to leave forbidden objects alone, but he's also young enough to distract away from whatever's causing the problem.
