I can't believe this hasn't been a problem until now!

We have lived in this house for 5 years. Sydney never discovered this, and Brooke never messed with it, until now. Brooke's bedroom door has a lock! She is in the phase where it's really fun to have people knock on the door, and for her to offer Girl Scout cookies and ice cream to us. In the midst of the fun, she discovered the neat little button that makes cool sounds when you press it. Luckily both times she locked us out of her room, Daddy was home to rescue us!
