I checked out Tracy's first book from the library when Lilah was 2 1/2 months, and realized I was already following some of the principles-- basically, she had a short activity time before sleep. I could just swaddle her and lay her in her crib and she would go to sleep. I never did a dream feed because she is breastfed and won't take a bottle, and how in the world do you get a baby to breastfeed while sleeping? I never could. She would sleep 8-10 hours at a stretch at night during this time, until about 4 months. I guess at that point I should have been transitioning her to a four-hour routine, but either the first book doesn't tell you that or I somehow missed it. What ended up happening, because I didn't know what I was doing, is that she'd nurse, play, nurse again, and then sleep, often feeding to sleep. She also hit a growth spurt and started waking hungry once a night, so I just kept feeding her. But it wasn't so bad, and didn't take so long anymore, and eventually that night feeding wasn't until 5:30 in the morning, so I didn't try to get her to go without a feeding. Everything was manageable until teething hit and she was waking several time a night, and needing to nurse to go to sleep. Also, around 8 months, she would try to stay up and party at bed time if she didn't conk out during the bedtime feed. It would then take an hour or more to get her to go to sleep. Arg! I had started out with an Angel baby who slept great early on and then accidental parented her into a night-time devil! Obviously, something needed to change. First, I night-weaned. I then found Tracy's newest book about a month ago, and wish I had had it from the beginning. I used P.U./P.D. and within four nights Lilah was sleeping 10 1/2 to 11 1/2 hours at night, with only occasional night wakings that needed my attention (she often calls out somewhere around midnight, and by the time I have gone to the bathroom and am ready for P.U./P.D., she has gone back to sleep on her own. She also is (usually) putting herself down for naps. I have my Angel back!
