Quoting Sami&Baby Silas:" I caught on to a lot of my friends being pregnant because they started liking my pregnancy updates and baby statuses all the time lol."
Unfortunately most of my friends will like any baby stuff being posted on facebook. So can never tell. I even liked a baby products page! Still nobody questioned it. I even put how broody I have been and this symbol (\o/) it means an angel, as well as updated my info to add my two angels this year with my angel from 8 years ago. Either people are being nice, or they don't care haha. I might do the whole 'see how long I can get away without saying anything'. I will only tell those that ask.
