This is an incredibly timely repost. Last weekend, my 8 month-old third kid was on the floor next to me while I was talking to my other kid when she started screaming. She had found a Mario Party switch cartridge under the couch and had it in her hand. I thought she had bit it too hard on her toothless gums because it had some saliva on it. She was more upset than I would have expected, and this has to be why. Thanks for reposting!
