Exclusively Pumping

Anyone else exclusively pumping?

Tried breastfeeding during the first week and it was painful and a mental nightmare. I could never tell if baby was getting enough plus I was always in pain. During the second week I have been exclusively pumping and feeding through bottles to better track how many ounces he is eating. I so far have been able to stay about a day ahead on my stock and have been pain free for the most part. Anyone have any ways to keep supply up but not have to pump as often during the night?
