I think Barb posted once about the percentage of babies who feed through a pg. It was low, I think something like 30%, but then the 70% also includes the mums who choose to wean, so it doesn't really tell you much about how many want to keep feeding but don't.

My DS1 weaned at 4 1/2 months into my pg, so we made it to halfway. I do know of lots of people though who have fed all the way through and tandem fed so it certainly can work out.

It's a tough decision I guess
