Don't worry I have trouble enough without a baby!
I'd love to read some short stories concerning Cadsuane. I think it had something to do with Cadsuane thinking she was high and mighty simply because she was Aes Sedai...my guess is Norla was stronger/more skilled and taught her her place.
She gained the shawl at age 26. Became a Novice at 15, six years as a Novice and five as Accepted. So if we say she is 295 and her last mistake was 270 years ago she would have been 25/26. I am pretty sure it was Norla.
