Pro parenting tip, and this is one that was all my friend’s idea but I thought it was brilliant – Meet Mr. Shut-up:

If you ever work out of the home, and you have kids, then you know that sometimes you may need to take a call and not have it sound as if you are working out of your home with kids. That is where Mr. Shut-up comes in. Let your critters know that, when Mr. Shut-up is on, it is time to be quiet or face the wrath of Mr. or Ms. Puts-a-roof-over-your-head.
