Mommy guilt

I thought that Hannah was ready to move from the crib to a toddler bed.  Yesterday, the railing was removed and we have an instant toddler bed.  She had a blast climbing on and off the bed.  She couldn't believe how much fun it could be to do that.  It all changed at bedtime. Most nights, bedtime isn't a chore. She will cry or fuss for a few minutes, but usually go right to sleep.  Last night she was screaming and hitting the door.  She flipped out.  She slept on the floor.  Same thing with her nap today.  I was hoping tonight would be better with a baby gate in the doorway instead of a closed door. Nope!  She started throwing things over the gate.  We tried closing the door again, but she was banging on it and frankly it scared the piss out of me.  So the railing is now back on the crib.  She only cried for a few minutes and is sound asleep.  The only highlight of last night is she did sleep through the night (well until 5:30 which is her new wake up time thanks to the end of daylight savings time.)  I feel awful about the whole process.  I don't know if I should have tried for a few more nights to see if she would adjust.  Maybe she wasn't ready, and it is good she is in the crib again.  I hate not knowing.
