Can you pump and still feed from the breast interchangeably?

I have had a hard time feeding my newborn (6 days old), mostly problems with him latching as he gets really handsy and pushes it out of his mouth and screams when he does that. I don't have enough hands to support him and hold his hands down and hold my breast. He's also cracked my nipples badly and I'm engorged on one breast so out of the frustration my husband and I realize a pump would be a lifesaver. Can I alternate bottles and breast? I mean I assume so but how realistic is it to keep up successfully?
