Escape

So I'm starting to see a pattern to my post'. The last post was about Myles escaping from the crib. This post is about Myles escaping from the HOUSE. I'm not kidding. He can reach, and has now mastered, the deadbolt. He can successfully get the front door deadbolt unlocked. He does it with ease and is quite quick about it. Before I know it he is half way to the street. I can't believe my not quite two year old is causing me so much grief. What is a mother to do?! I guess I need to get a safety latch at the top of the door. I don't know what else to do. He's too smart for his own good!
