You can also try breast massage, and (this is going to sound crazy but).... before feeding her lean completely forward and shake your breasts (like a shimmy?) I know sounds crazy! but it helps to bring down the milk by working with gravity.
As far as the breast massage, it can also help to bring the milk down easier so she will get milk quicker, and to maximize milk removal when feeding (along with breast compressions) to help increase milk supply. You would use your finger tips to start at the top of the breast and rub downward towards the areola. Work all around the breast like you could imagine it as the spokes of a bicycle wheel, going down each spoke. Just remember to support the breast on the opposite side. So if you are working on the top of the breast, use your other hand to hold underneath to provide support and so on. Go around 2-3 times. You will probably start to leak a little while doing this, but it will help eliminate her frustrations because milk will be there right away for her to drink.
