Hello, Everyone. I have done plenty of reading here, but this is my first post. It's a pretty small issue, but I wanted some opinions. I have two toddlers that have a sitter who comes to the house a couple of days a week to watch them. She is a great sitter, and we are lucky to have her. She gets to our house pretty early, and has been using our coffee maker to make coffee in the morning, and drinking it out of an open mug. Being the worrier that I am, I am concerned about the possibility of burns. I came up with the idea of buying her a travel mug to keep at our house and have her use when she wants to drink coffee. Am I being unreasonable? What are the chances she will find this offensive? Has anyone else done this?
