Goodbye, crib. Hello, bed! Baby is happy to move on to the next phase of sleep furniture. There’s so much to do on a big, soft bed — lie on it, play on it, bounce on it! At bedtime, Daddy tucks Baby in, Mommy says good night, and there’s so much space, and the bed feels so . . . different. What now? Trepidation gives way to a good night’s sleep in a celebration of a familiar toddler ritual.
