Although my nap problem is gone since I’ve used sleep training method with How to teach a baby to fall asleep one – great short book from http://www.parental-love.com. Since then Beth sleeps longer at night and naps better. I believe it was about learning to self-sooth. But it was exactly 45-50 minutes she used to wake up!
