I would say that 6 feeds would be the absolute minimum for his age, but if he's eating really well, then it could be enough. You want to make sure that:
1. He has at least 7 very wet diapers during a 24 hr period.
2. Comes off the breast satisfied and is able to last at least 3 hrs between daytime feeds.
3. Is meeting developmental milestones and sleeping well.
4. Is gaining weight well.
If that is okay, then he's probably getting enough.
