So, I read what I needed to at this stage in the game (4 months into parenting), and I will go back as needed, as The Bean's habits change.
Ferber often gets a bad rap, and most people who know of him think he's all/just about letting your kid cry it out. The book is actually more nuanced and compassionate than that, and I found his discussion of sleep cycles pretty illuminating and helpful. My baby can fall asleep without nursing, which is great, since it not only means Daddy can be The Bedtime Master, but also that my baby knows how to go to bed on his own, self-soothing and all that--this is a skill he will need for life! (I should say that I figured out he could fall asleep without nursing pretty much by accident; he just fell asleep one day, on his own, and it was clear he didn't need my boob as much as I'd assumed.)
Ferber helped us realize that Dixon doesn't need to eat at 10 pm, 3 hours after he's fallen asleep. It's more likely that he's entering a new sleep cycle, and that he can figure out how to get back to bed on his own. On the first night after reading this book, he cried at 10:15, and my husband and I waited, breathless, on the couch, to see what would happen if we didn't run to his rescue. 20 seconds later, he was fast asleep and didn't wake up again until 1:30! He hasn't woken at 10-ish since. Now we're trying to figure out which night-time feeding is truly necessary--for his belly, for his soul--and which one(s) can be eliminated. It's a bit touch and go, but we're learning. I'm trying to balance some of Ferber's ideas with my own instincts. I'm hoping Ferber can next help me get some more naps into my kid! When baby sleeps more during the day, the nights are far more peaceful.
This is an informative read for anyone with young children who is struggling to figure out nap schedules, bedtime routines, night feedings, and so on. Don't be afraid to Ferberize! (God, that word--it's scary, right?)
And, sometimes it's okay if a baby cries. My mom said I used to cry for 2-3 minutes every night before bed, and then slept 12 hours straight. I needed that little cry, to expend some energy before my nightly coma. Don't knock it! Also, don't let your kid cry for hours while you surf the internet. Jesus.
