At 6 months, our daughter Audrey was still getting up every 2-3 hrs at night and would hardly take an afternoon nap. We were getting pretty tired, so tried crying it out and it failed completely (we used it for our older son and it worked fine). Crying it out led to Audrey getting up 2-3 times a night, one of which she screamed inconsolably for 1-2 hours, even 3 a few times. Her dad and I divided up the night and slept in different bedrooms to try to get enough sleep to survive. We read every sleep book (Including "The Good Night, Sleep Tight Handbook") and tried so many things. Finally at 9 months, our pediatrician gave us Anna's contact information. Anna helped us figure Audrey out. It was an iterative process, taking the results of one change to figure out what else to change. We saw steady improvement and after about 3 weeks Audrey settled in to sleeping about 11 hours straight every night and taking 2 solid naps, but the key is sticking to Anna's "rules". Anna has helped our family so incredibly much. I would recommend her help to anyone, from someone that has a few questions about childhood sleep to someone who is at their wits end.
