Well we usually keep it mellow in the evenings, we'll play with her stuffed animals or read a book or take an extra long bath so she can play in the tub, etc. Honestly she turned into a terrible sleeper once we moved her into the nursery at 7 months and we're lucky to get 2 hours of continuous sleep out of her. Especially when teething.
We tried doing the gradual withdrawal for a week or so, but it got to the point we were so tired we'd end up falling asleep on the floor in her room. So big fail there.
I'm hoping that transitioning to 1 nap will help her sleep better at night... plus she starts day care next week from 8am-noon, so lots of play buddies during the day.
