ER has always had bedtime idiosyncrasies.She slept all swaddled up a lot longer than most babies. Then when she finally outgrew her swaddling blankets, she had to be in a sleep sack. Next she would only sleep on her belly with her legs tucked underneath in the exact same corner, every time. That stage lasted for over a year. It was finally replaced with, needing her legs and feet to be sticking out through the slats in the front, when we changed her crib into a toddler bed.
Then came sleeping in bed with every single baby she owned, we thought that was over when for a brief week or so she wanted to sleep in a completely empty bed. Apparently, it was just a brief respite. Now she wants it jam packed again, and for the last few months she's added a new addition to her bedtime rituals.
