First of all, your girls are so adorable! I could look at your blog all day long. But that is not why I am paging you.
I noticed in your blog you have some kind of contraption on your door handle. My DS loves to enter places he shouldn't and can open all handles in our house. With the twins coming, I am setting up Fort Knox so he can't get into trouble while I am feeding, changing diapers, etc. I bought something from Target but you have to take the entire handle apart and install it. NOT FUN! Do you mind me asking where you got your toddler proof contraption? TIA!
