DS2 was having, on average, between 6-8 bf's a day at 9 months...sometimes more if ill, teething, etc. There isn't a they must have x number of feeds a day, it's a how long is a piece of string type thing; some may only be having 3, others, like mine many more.
I am a big believer in doing what works for them and letting them set the pace. Having said that, you have to do what feels right for you; if you think he won't miss them then try and cut them out. At 12 months we were still averaging 4-6 feeds a day, but 7 months later and I am lucky to get one feed a day, if any.
