Flipping the crib to the higher side out bought us just a few days before he figured out how to climb out that way, too. That in combination with him fighting bedtime more & more, plus middle of the night wakings, had us finally bite the bullet.
So we bought him a new Cars pillow yesterday & we converted the crib this morning. We had to rearrange things a bit to gate off his humidifier & space heater & we also put a child safety cover on the door knob.
He napped in his big boy bed successfully this afternoon for an hour & he went to sleep tonight with just a minor protest.
FX he makes it through the night without incident!
