Just sticking my oar in ...
I do not get as aerated as some in discussions of early weaning - DS1 was weaned at 20 weeks, DS2 at 26 weeks. DS1 was driving me demented with his demands for more bf's by 20 weeks (although looking back, I think this was an extended growth spurt, but coming on top of months of sleeplessness, it finished me off and I decided to wean early), DS2 wasn't, so it was pretty easy for me to get to 26 weeks with him, and I DO know what it's like when you really feel that milk is not enough, and those last few weeks to get to the 26-week mark feel impossible to get through.
But weaning at 10/11 weeks is just barking mad. I know the guidelines are "only" guidelines, but so are the dosing instructions on the back of the Calpol bottle and I doubt you'd get many people thinking "Oh, no, I won't pay any attention to those, I'll give my 3-month-old a much bigger dose because she's having so much trouble with her teeth and I know my baby best" surely?
I also post on BC (so shoot me) and am lucky enough to be on a genuinely friendly birth board with some very sensible women (not "ladies" - yuck!) posting good advice. But I also lurk on DS2's birth board (he is 8mo), and this had masses of people rushing to wean at the earliest possible opportunity, and the usual asinine "You know your bubba best, hunni" sort of stuff.
