My grandson fights the shower with all his being, and he always has. It used to be the physical sensations, now it's doesn't want to leave the iPad, automatically goes to "NO!" when you ask him to do pretty much anything. We have to bribe him with a game download or extra screen time, then make sure his hair is actually wet when he gets out of the shower, or he hasn't dumped shampoo on his head, then didn't rinse it out. Goodness but I'm dreading the teenage years.
