I read an interesting article last night on why you shouldn't wait to tell people until 12 weeks (basically your boss will think you're a slacker going to the loo to pee 5 times an hour and hiding in there feeling sick for days at a time, the stress of keeping a secret being bad for the baby, and miscarriage shouldn't be like a guilty secret or kept hidden so women think its just them that suffers when they could get support from other women around them)... while I found it interesting and agree in principle we're just not ready for the world and his wife to know, need a bit of time for it to become real for us just yet.
