I feel your pain! I also have a 2 week old DS that wont sleep unless I am holding him (I'm breast feeding too) and it is exhausting - even making a cup of tea requires planning and if I need the toilet I have to let him cry for a bit in his crib
- I also think I am starting to smell a bit as I haven't had chance to have a shower for a couple of days
(I'm on my own all day so no one to hold him for me)
I have tried the moses basket, swinging crib, cot, swinging chair, pram - the list goes on. I don't like having him in my bed as I am worried he will fall out or suffocate, or I will squash him etc but its the only way for me to get an hours sleep. I keep waking up though paranoid that I have killed him. I do swaddle him as he gets wound up when his hands wave around. I have resorted to giving him a dummy which he likes but will only have it if I put a little bit of infacol on the tip. I am probably ruining his teeth or something but I have been desperate.
The best thing I have is the swinging chair, as sometimes if he is properly asleep I can just lay him in it, swaddled and turn it on and get a few minutes quiet time (like now) but its quite hit and miss on whether he will tolerate it for 5 minutes.
He feeds every hour and 15 minutes or so, but the only time i've got a couple of hours sleep in one go was when I fed him from both sides and he was so full up he just crashed out 
I do have 2 older DC, they are 7 and 9 and I can't remember what it was like with them but I take comfort in the fact that they and I survived so this difficult stage can't last forever. I adore my newborn, I keep telling myself that he will only be so tiny for such a short time and that if i'm what he needs then so be it. One day i'll be desperate for a cuddle off him but he will be to busy, out, or cuddling his girlfriend so i'll make the most of it now
