Forgive me if I'm stating the obvious here but I really wanted to make sure that someone mentioned the danger of premature weaning at this age. All that distractability can really create a negative spiral with mom's milk supply decreasing and baby being even less interested in nursing. In my limited experience this phenomena really seems to peak at this age but tends to get better in a few months as babies seem to get a little more interested in nursing.
As Naomi hinted at, night-nursing can make a really big difference at this stage. If baby is able to nurse a lot at night, there may be little effect on your milk supply and you may not have to concern yourself too much with trying to increase daytime feeds.
I hope that Naomi's link will be more helpful than I've been! (Actually, I've read it and know that it is.
