I hope you have a trial period in your contract so that if it does not seem to be working out, you can terminate without notice. I agree with your husband in one way...it will be hard in the beginning no matter what age of kids you take. However, on the other side, I would not be putting up with any bad behaviour either from a school-aged child. Not only will it stress you out, but it might start to rub off on your own kids.
