For months, there was nothing in the crib except a bumper. Now, at 19 months, Little Man sleeps with an entire array of stuff including, but not limited to:
Fox in Socks (his fave. Loves to sleep with it)
a stuffed gargoyle (so cute!)
a baby bat
At what points did SIDS stop being an issue? I dunno. About the time he was trying to use the bumper and heel hook his way out.
