I marked this as "#1" as I expect that there will be other installments. ;)
So, a little bit of background before I go into why Emily is absolutely brilliant.... Before she was born a friend of mine gave us a gift of a lamb crib toy thing. It attaches to the inside of the crib and, when you push on the lambs stomach, it plays music and does a small "light show". Just within the last couple of weeks have I started to sift through the various toys that we have (as Emily is just now started to "play" with things) and I found this. I strapped it into her crib and tested it out. Fifty-percent of the time it doesn't actually do anything for her sleep, but 80% of the time I can get a 5-minute break to pee or make myself a sandwich while she watches the lights and listens to the music.
Well, last night, at 4 am, I woke up to "Old McDonald" coming through the baby monitor. At first I thought that she had accidentally kicked it and turned it on. But then it went off before it finished it's cycle (you can stop it by pushing the belly again). I then expected to hear Emily start to cry and have to get up to get her. But, I waited and nothing happened... for about 5 minutes. And then "Mary Had a Little Lamb" came on! And then I heard Emily do a little "giggle" (her happy noise... she's trying desperately right now to figure out how to laugh). This went on for HALF AN HOUR! lol Music on, music off, happy noise. I was lying in bed just listening to her with a big ol' grin on my own face. Finally, at 4:30 she started to whimper and I went in to feed her and put her back to sleep.
Just goes to show that my kid is a frickin' genius and is starting to figure out cause and effect!
