Nursing too often?

For those that do, how often are you still nursing your LO? I work from home and my son stays with me all day. I nurse him first thing in the AM, before his first nap, when he wakes up from nap, before second nap, after second nap, before third nap, after third nap, and before bed. He's always been in the lower percentile for weight so want to give him as many opportunities to eat as possible. He also gets three meals a day. But I'm starting to worry that it's going to be very difficult to wean him, which I plan to do at 1 year. What does your nursing schedule look like?
