8 months is a well known developmental milestone for babies. I always check tickers when people ask about sleep and it's always around the same ages!!! During developmental milestones, babies often sleep less, cry more, are more clingy, feed more and parents often have fantasies of throwing baby out the window LOL

Remind yourself that it will pass, it's not permanent nor is it a bad habit you have formed. Don't forget Pink McKay's book is coming out July 3rd and it tackles all this stuff - it's gentle focused, but helps you with suggestions for issues such as this. I am really, really enjoying reading it but of course, unfortunately I can't give away her secrets before the book is launched!!
