Where is Elijah....

My 3 year old, Elijah, may struggle with his speech but he is quite a problem solver.  He loves to play with the water hose on the patio and apparently was determined to do so, with or without us.  One Sunday morning at approximately 7am, he crawled into bed with my husband, my 3 month old, and I.  As usual and we all went back to sleep and I was hoping for maybe an extra 30 minutes of rest before he started saying "Mama, wake up.  Are you hungry?".  The next thing I know, I wake up feeling rested.  I knew something wasn't right and my husband sat up and noticed Elijah is not in bed with us.  He jumped out of bed to go find out what he was up to.   Assuming he was just in the living room playing, I rolled over and checked my phone and panicked when I saw it said 10am.  About that time, Noah calls out to me that Elijah is nowhere to be found in the house.   My precious, active son was missing. My heart stopped.  I felt like I couldn't breath. Terrified, I was already thinking of all the things that could happen.  We have a pond with alligators behind our apartment, a pool down the street, tons of neighbors….  I flew out of bed, completely frightened and ready to start looking for him.  As soon as I reached the living room, Noah was dragging a soaking wet Elijah down hallway to his room as he scolded him.  Thankfully, Elijah had been found and had come to no harm.  He had been playing outside on the patio to play in a thunderstorm – it had been pouring rain with lots of lightning all morning.  Noah’s only clue to his location was a chair pulled up to the sliding glass door.  Apparently Elijah had pulled the chair up to the door, pulled the locking pin out, hid the pin, unlocked the second lock, went outside, and closed the door behind him.  He wanted to play with the hose on the patio so badly that he figured out his escape.  We can only guess to how long he was out there….  It took hours for my heart and Noah’s to return to normal.  There is a third lock on our sliding door and Elijah cannot reach it or figure it out.  It's also transparent, so he hasn't even noticed that's why he can't get out again.
