When and how did you do it?

DD is 7 weeks tomorrow and sleeping great in the RNP at night (generally 10:30-4:30 and then back to sleep til 8ish), but I don't want to wait too long and then have a tough transition to the crib.

DS slept in the nap nanny until 3.5 months until we put him in the crib and swaddle weaned cold turkey, which went surprisingly well. But I'm not sure I want to risk waiting that long again!
