Now I Lay Me Down to Sleep??

How is it that you can be falling asleep on the couch but when we put you in your crib you are wide awake and refuse to go to sleep? I hate the sound of you crying but I know how badly you need a nap so I am sitting here listening to you cry and knowing that eventually you will fall asleep. Nap times have become a struggle lately which is hard for me. When you were younger you slept so much that I never figured we'd have a problem getting you to sleep. Now you will take a nap in the morning without too much trouble but you almost refuse to go down in the afternoon. You'll be going through the afternoon with purple eyes and a really grumpy disposition but you just won't let us put you down. I now understand all those stories my parents tell about me and know I am getting back everything I did (or didn't do).
