My house is a mess more often than not. I live with busy kids. Plus, I’d rather spend my time doing what I love than spending it cleaning! I was quite happy when someone pointed me to a study about creative people being messy.
So don’t worry about the mess in your own home when I come in for your session. I will work around it and ignore it, or if it’s an important part of your story, I will document it. When your kids are older and have left your home, you might actually miss that time when your house was full… of life!
