I don't think urinary incontinence has anything to do with breastfeeding.
It has a whole lot to do with multiple pregnancies! And in my own case, it
didn't go away with weaning (as one wouldn't expect it to if it had nothing
to do with bf). Kegel exercises help immensely -- and always remember to go
pee before jumping on the trampoline. ;)
