Oh Pacita, ime this is the hard bit, so you have my sympathies.
Firstly, keep reminding yourself that she is very very young and is getting to grips with everything. She's been through a HUGE change too.
I have no idea if this works, but keep her in the daylight when it is day, then when you are feeding at night keep the room quiet and dark. My theory is this helps them get used to day and night, and it's what I done.
Feed, feed, feed and feed some more during the day. Again, my theory is pack the milk in during the day so they don't need so much in the night.
When it gets to much, hand her over to dp. I often found my frustration was mimicked by the ds's. So after a feed I would pass them to dh to do the settling/walking about.
Your supply is still establishing itself, so it may be playing catch up as your milk has only been in a few days. Try and tell yourself that the constant attachment to your breast is a good thing - it is stimulating your supply.
She is satisfied by your milk, but she also wants to be close to you, and being attached to you is probably the best feeling in the world to her. It is bloody tough though.
Hang on in there, it will get better
