Hows this? I read your original post and thought: How lucky, she slept through up till Christmas..
DS got worse from around 6 months too. The really bad times lasted about 6 weeks. Then we started co-sleeping and things got better. Had a couple of good weeks... and then he started teething. Mostly I'm just trying to ride it out - it's gotta get better.
Are you feeling quite resentful toward Shel about this...? Cause I probably would be in your situation. I could punch my DH sometimes when he tells me about how tired he is... But it's my problem really cause I don't let him get up for DS anymore cause DS just wants boobies and they'd both be up for hours whereas I can get him back to sleep quickly. Am now mentally preparing myself for night weaning once he's 12 months... maybe...
Really do hope she settles down for you...
