Meg, have you tried playing with her before a feed?
I found that when this happened with Alexander he was just over tired and that's why he was such a cranky pants. If I put him straight into bed after a day feed we don't have too many issues, he tends to just drop off. Sometimes he babbles at the curtains or the wall, but without the extra interaction we then get a good sleep. I alos find that now we do this, he wakes before he is hungry so we play first.
It may also be just that she's having a bit of a growth spurt? Alex was like this around six weeks too and just constantly wanted cuddling. HAB was great for this time but he's barely been in it since he was eight weeks.
Personally I think play first works better because you can play and then feed-to-sleep... or til dopey at least! Hope it gets better for you soon
