Limited success - M was up at 5 am and went back to sleep without nursing. But he was up for the day 45 min later.
2 yo is on the young side for being out of diapers, but not unusual. Especially for a girl. Several of the 2 yo girls in M's preschool class are either fully or mostly using the potty.
Just like Lynn said, 2 is on the young side. K was done between 2.5-3. I think in Lu's case, having K around to emulate and her own readiness (plus my willingness to bite the bullet and just clean up the oopsies), did the trick.
