We used Ferber with our first baby. I can give anyone who needs the basics of that method, but I'm not sure it's the right choice for our second baby. DD can fall asleep by herself, but she's starting to lose the skill. She's 5 months and sleeps mostly in her crib. She's still sleeping in a merlin. I'd love to be able to set her in her crib and have her put herself to sleep like her brother. Any suggestions for other options before I do Ferber instead?
