A few weeks ago, I did the Ferber method with my baby because he was waking up constantly during the night. He sleeps so much better during the night with an average of 10 hours a night.
His naps are a different story. He only takes 2 per day and he will only sleep 30 minutes each time. He wakes up crying and I know he is still tired. He stands up screaming at the top of his lungs. I have let him cry a few minutes to see if he will go back to sleep, but he doesn't.
