Can you have someone care for your kids outside your home while you interview. Kids almost always act up when they see we are busy (notice when you are on the phone they are suddenly into something they are not supposed to be) If not, can you speak to him about being a big kid and being Mom's helper? If my child was that young, I think I would have them out of the home or see if hubby was available to help. Sometime in the middle of interviews I will call my hubby and daughter to come meet the potential client. I do this so she can get a feel for my home, family and see we are normal folk in a happy home so hopefully she can relate to us.
