We are nap training with Ferber (did Ferber for night 3 weeks ago). 30 min cry limit or 45 min total time limit from set down before we give up on a nap. With the exception of the last nap of the day we rock if nap fails rather than get her up because we don't want to head into bedtime too overtired.

Day 1:
Nap attempt 1- fail (just got her up to play for 30 min and try again)
Nap attempt 2- 20 min until she fell asleep and slept 45 min
Nap attempt 3- 20 min until she fell asleep and slept 2.5 hrs(!!)
Nap attempt 4- failed and rocked, but wouldn't calm down enough to sleep.

Day 2:
Nap attempt 1- 40 min until she fell asleep and asleep for 45 min
Nap attempt 2- 25 min until she fell asleep and asleep for 1 hr 20 min
Nap attempt 3- fail. Got her up to play for 15 min then rocked her and she slept great for 1 hr until I woke her up.

Today is day 3:
Nap attempt 1- fail
Nap attempt 2- 35 min until she fell asleep. Slept 1 hr 40 min until I had to wake her up
Nap attempt 3- 30 min until she fell asleep, slept 25 min and woke up crying/angry and now she is cranky.

Sigh. It seemed like improvement from day 1 to 2 and now today is worse than day 1 it feels like. Are there normal regressions a few days in for nap training like with sleep training? How fast did nap training work for you?
