My first kicked constantly, never, ever, EVER stopped! I was completely terrified I wouldn't sleep again as DH is a night owl, I'm a lark... Completely light sensitive, I would fall asleep at4.30 in winter when the sun goes down if ideas allowed to!
But DD was born... Cluster fed and barely slept for 4 weeks...maybe an hr a time. Then settled feeding patterns at 4 weeks, slept for5 hrs at a time, then we moved house at 8 weeks (don't EVER do this with a new born) and had space for her own room. (At the same time she started top up feeds with formula, I was quite ill post natally and my milk got less and less). Her bedroom was next to ours and when we were lying in bed I could see her in hers very clearly. So we tried it for one night, mainly because our bed wasn't up and floorboards unsealed and dusty in our room. Slept for 10 hrs straight at 10 weeks... Never looked back!! Even now, at nearly 5 years old, she will sleep for 12-13 hrs straight at night.
My other DD arrived two years later, didn't kick so much (I don't think, looking after DD1 so didn't notice as much). She was in intensive care for a week then came home, and wouldn't ever let me or my boob go, totally refused. Co-slept tills year consequently, I barely slept as I fed on demand, and she Waac demanding!! I didn't mind, I had the luxury of being at home. Daddy didn't exist in her mind till she was 10 months, she wouldn't take solid food from him or anyone else. He was very shocked as DD1 adored him from the word go.
But as soon as she hit a year, she self weaned, just are solids with gusto a and would sit in her bumbo seat cooking with daddy till all hours!! 
Sorry for long post, trying to get across that for both my DD's their sleep pattern was basically linked to food.
DD1 was 9 lbs 4oz, DD2 was 8lbs 13oz, I think birth weight helps too. And also going with the flow. I found people obsessed by routines etc and not relaxed always had less sleep.
