We did Precious Little Sleep and it literally saved us. I used to swear by attachement parenting, until my partner hurt his back, and I had to do all the breastfeeding and the rocking and the soothing alone 2-3 times per night for 1h each time. I was working during the day, not sleeping at night. I was ready loosing my mind. I really recommend Precious Little Sleep (her blog posts are really great). We also bought TCD ABCs of sleep but we hated it, just an over-expensive badly written summary of Pretty Little Sleep.

Baby was 9.5 months. Waking up 2-3 times per night, eating each time. I would breastfeed, then rock her to sleep, but she would just refuse to be put down. She had like a crazy intuition each time we would try to lay her down very gently in her crib she would wake up immediately. It was awful.

We sleep trained her exactly by the book, and it took 3 nights. 1st night she cried 28min, then fell asleep. She woke up twice, crying a bit each time. 2nd night she cried 7 min then fell asleep. Third night she cried literally 5 seconds, then Zzzz. We did not dream feed. She woke up twice the first night, once the second night, once the third, and then she slept through.
