Share your experiences! Have you had a baby that wasn't sleeping through the night at 9+ months? Are they sleeping through the night now? How long did it take to change? What did you have to do? Did it happen on it's own? Are you currently struggling with a 9+ month old that won't sleep through the night? How do you cope? Are you taking it day by day? Are you losing your mind reading every sleep book you can?
