Drivenmad - I so feel for you. DD was a nightmare - day and night. Your post brought it all back for me - the hours of HVs giving me 'advice' that didn't work and the sleep clinic lady who ended up admitting it was beyond her. DD would HOWL unless I was holding her ALL THE TIME and it drove me insane. I loved/love her totally, but it sent me to the edge.
Well done you for getting ADs, btw. I resisted but a year later they have really helped me.
One thing that also helped was buying a SWING!!! If you're in South London CAT me and you can borrow it. It meant she actually NAPPED!!! Ok not for very long at a time, but it did mean I didn't have to be dead on my feet, pushing the buggy round the neighbourhood to get her to sleep.
All I can say - because it is true - when you have tried swaddling and dummies and white noise and Harvey Karp and the cranial osteopath (sorry didn't work for us but I was desperate so tried it as it works for some people) etc etc and everyone keeps telling you this and that...
just remember IT WILL END.
I won't tell you when it ended for us, as it might make you upset as it took a longggg time - but DD is now 18 months old and we have been having proper sleep and proper rest for months now and everything feels normal again. I never believed it ever would. At one point I was hallucinating from sleep deprivation.
(I also wanted to smack all my friends with their babies who 'settled' at 12 weeks... and liked to imply subtly that DD's behaviour was my fault )
I remember collapsing/sleeping on the kitchen floor one night because I was so exhausted and it was for some reason the only room where DD would go quiet for a bit!!??! Got about 30 mins sleep that night.
It doesn't make you a bad mother to be exhausted and fed up. You are human and it is unbearable while it's happening - I know.
((((hugs))))
(Sorry for the post-a-thon but I soooooo feel your pain!)
