I'm the same, I've noticed my belly isnt as wobbly, i know im a bit further along but I've read its quite normal the second time around and as my 1st time was 11 years ago its taken a bit longer for my body to remember what to do
I even think my belly has got a bit bigger as at work yesterday I had to change into my gym pants half way through the day as they were a bit tight (they weren't before I got preg) and starting to hurt
