Breastfeeding - fine during the day, nightmare at night, help!

What positions do you use. I used to find my flow was a lot faster at night and had to feed leaning back.

That sounds like a tricky combination of cluster feeding (inevitable and necessary, but will pass) with tiredness. I found an immediate improvement when I started to focus more on subtle sleep cues through the day. Look for these from 30 min awake time. A baby of that age should rarely if ever be awake for over an hour and whatever it takes to get him to sleep, do it. Better day naps = easier nights.

Ah yes - newborns are so adamant that their hands are somehow integral to the breastfeeding process when all they do really is get in the way!! I found a good swaddle helped to keep DS's hands at bay along with a firm rugby hold. Plenty of regular winding too as the fussing often makes them take in lots of wind. You are in the middle of what I found the toughest time but after 3-4 weeks they get a bit better with the cluster feeding.

I remember googling baby handcuffs at this point

It could be overtiredness. It's your worst enemy. Babies often get over tired but don't realise it, get very confused and seek comfort on the breast thinking they want a feed when they don't. If your baby isn't actually taking a feed, try resettling- swaddle, rocking, sssshhh ing - whatever you do. If not settling, try feed again in half an hour.
