Breastfeeding question! How much time is enough?

Tracy

I have a 6 day old, and he latched wonderfully from day 1. In terms of nursing time, I’m having a hard time figuring out what is enough. He will latch for 20 minutes altogether, sometimes 17-18 minutes and I worry it’s not enough. Currently, today he has had 6 wet diapers and 7 bowel moments, so he’s seems to be getting enough, right? I feed him approximately every 2-3 hours.
