Please please help. I am in apt hallway with my toddler. Tornado coming this way. How can I keep her with me?

Right now? You're in the hallway right now? With a toddler? And on the computer? I'm suspecting this situation has resolved itself. However, doing a swaddle or simply holding her will suffice. If the child is scared, as is the case in large storms or high winds with noise, they will usually cling to you.
