Tear free my arse!

I'm at my wits end with Kaden this week. I caught him with the sunblock and took it away and told him how dangerous it was and not to touch it again. Well then I was running around the house trying to get us ready to head to the mall and I heard Micah crying. When I got in the room his eye's were bright red and his nose was running and Kaden was standing there with the sunblock in his hand. I called poison control and they told me to flush his eyes out with water for 5-6 minutes. The poor kid was screaming the whole time. They told me his eyes should start to look better in about an hour but would take awhile to completely clear up when he woke up from his nap at 4:30 his face was still pretty red and swollen so I called the Dr. The nurse told me to use cold compresses and give him some benadryl. Poor guy still looks a little puffy today but he's definitely much better.
I'm sure Kaden wasn't trying to hurt him. I'm guessing he was just trying to put some sunblock on him but I've been having a really hard time with him defying me lately.
On a side note it was banana boat kids tear free. Not so tear free if it gets sprayed directly into your face though. I think we're gonna stick to the lotion from now on.
