I can hypothesise either...
a) since I'm fat anyway there's a lot of extra space to be 'taken up' by the growing baby before it pushes out (and people will probably notice relatively small changes less on me). On the other hand,
b) since I don't exactly have abs of steel it might all start to hang out earlier than someone with a taut stomach.
Not really bothered either way, just interested to know when I might show. Am a comfortable size 20 and 10+2 with my first. So far my tummy feels more solid than usual and I find it harder to 'pull in' than before.
Anyone got any good guesses when I might start showing?
