My almost 7 month old has been rocked, shushed, patted, nursed, bounced to sleep through colic and up until this point in her life and DH and I are at our wits end. She's 15 pounds (so rocking is not easy anymore) and bedtime is a battle that literally takes HOURS every night. Then after our bedtime battle she is up multiple times a night sometimes for extended periods of time requiring the same super movements to get back to sleep. It's exhausting and we are SO ready to sleep train. We tried CIO with checks a month ago and it was a disaster with the crying getting worse not better. What sleep training methods worked for you? How did it work? What did you have to do? Any sort of guidance at this point would be great....
