What do you say when asked this question? I don't get all political and go into the many many many benefits to me and DD (or the fact that I just WANT to carry on) - I just calmly say 'oh till she's at least 30'! people giggle nervously not really knowing how serious I am. TBH, I can't say, DD is just one and I would like to carry on until she is at least two but maybe I'll change my mind next week - why does the whole world think I know the answer anymore than they do? Would love to hear what other MNetters say when faced with this question.
