Currently working on night weaning DS. He is 14 months.
We were doing a feeding at a time, and knocked out his first feeding (which was around 9:30) and got him to midnight.
He is teething, and has regressed to 10:30 (DH still comforts him, but he is often up another time or two between then and midnight).
Once these teeth break through, we will resume working on it. I go back and forth between doing a feeding a time, and all at once with DH comforting him each time.
I would love to hear people's experiences. DS is on the spirited side, and is a very determined little guy. Getting him to midnight was not pretty.
