Yep - I'm with the others. We used to sit with her forever crying to get her to sleep. All hours of the day or night, and it didn't stop at 8w.
I will say that I probably started to interpret her a little better at about the 10w mark, and alot of what I had been told started making more sense, but it was still alot longer before we could settle her.
We also had a baby that had to be rocked or patted to sleep for along time. She has always woken up as soon as the pram or the car stops, and thats that. I used to also have to feed to sleep for a long time too.

Eventually, when the dust has settled, you might want to worry about a routine or your own system for getting your one to sleep, but in the meantime dont be afraid to offer lots of cuddles for some rest time.

Big hugs - it will get better slowly.
