yes, totally bigger second time around! mine finally "caught up" to previous pregnancy around 24 weeks, but until then I was so much bigger earlier the second time around!
I was just like that, too! When I compare my pg pics for both pregnancies, I look about 4 weeks further along with Jack compared to when pg with Ethan.
Re: wow 15.5 week belly pic Yikes!
You look great! And yeah, I think I started showing about an hour after conception with Tess. I think I broke out the maternity clothes at 8 weeks.
