you sound like me! lol you are doing great!
i use the medela pump in style advance. ( using it atm

)
what i would do was pump after nursing her (both sides at the same time)
i would try to pump while she ate...
try nursing her in different positions
i now pump once in the morning, in the afternoon and right before bed.
she wakes around 4 and i pump then too
we gave a lil formula in the begining to..and all i can say about that is .....put the stuff away!
she will get what she needs when she needs it.
also before you pump (tmi maybe) play with your nips a lil or hold a warm rag on them
HTH hand in there! listen to these ladies they know their stuffs
