My suggestion is to just hold her Olivia was like this and still is. Also don't let her fall asleep after just a few sucks. It is so hard to wake a sleeping baby. IMO she is waking often cus she is hungry as she isn't get all the rich creamy milk only the foremilk..

My sister used to wake her son with a damp cloth rubbed on his face. I just sit them up stroke them talk to them and eventually they stir and if they don't then try again next time they wake..

also when she is feeding keep stroking her face and rubbing under her chin to keep her stimulated enough to suck..

Hope this helps
