We put her to bed as usual. We had a clue something was up because she flipped onto her front when I put her down in the crib. She used to always go to sleep on her back. We said our goodnights and before M. was even down the steps we heard the "Mommy, Daddy, Mommy, Daddy, Mommy, Daddy!" So we walked away and ignored it. It lasted thirty seconds and she quit. She must have quickly decided she was tired after all.
