I can sympathise, as I was still doing BFs about every 4 hours up until 8 mths - and it seemed that everyone else's babies were sleeping through etc. I wondered whether he would ever stop bf-ing.
However a month later and his solids had increased to the point where he was taking less milk and my production dropped off. It might just be worth trying to hold on in there for another few weeks, as your DS will probably start taking more interest in solids and you will not be the main course anymore.
You are doing an amazing job, and are one of a very few number of mums who are still breastfeeding at this stage - but it is the gold standard to which lots of mums aspire. If you do want to pack it in more quickly, don't feel too bad about it - your DS has had the best possible start.
If you read the kellymom.com site there are papers which discuss the benefits of extended breastfeeding (beyond a year), but if that is not for you, you have given your baby lots of health benefits already, had the pleasure of feeding your baby, and can take a lot of pride in growing that 30lb-er almost by yourself!
Well done
(One of the funniest things I heard was a woman who was desperate to wean her baby from the breast, who drew an angry face on her tit - which apparently worked!!)
