Sleeping with your corn bag....beware!

My kids have always went to bed with their corn bags, especially in the winter months when it is downright chilly. However, lately my son has been waking up in the wee hours of the night asking for his corn bag to be warmed. Now, I love my children, however getting up at 2:00 am to warm a corn bag is something else. Try to reason with a 4 year old in the middle of the night, it does not work. I held my own though, and did not warm it. Once you start something it will become a nightly ritual. I told him that the only way to get his corn bag warmed at 2:00am is 1) to be spitting up 2) to have the swine flu 3) to have a major injury. So now when he gets up we go over the list and of course the answer to all the above is NO..he goes back to bed. Hopefully, he will get over this and sleep through the night...I am getting weary!
