FTM BREASTFEEDING HELP!!!!

Erin
My LO is 1 week old and he's been latching since day 1, but ever since our second night home he latches but is very very fussy while doing it. He gives up on trying to feed from the nipple so I decided to pump and start bottle feeding. I can pump up to 4oz at a time from each boob, but I really want my LO to start latching again. Is there anything anyone could recommend me to start doing differently.
