AAAAAwwwwwww, cute schnoz in the first picture!!!!!
Chubby????? What a cheeky thing to say, you are only 20 weeks, he/she will be totally balanced out before they arrive in the world!
At my 20wk scan my babies legs were measuring extra long dating them at 22 weeks but everything else was showing as 20 weeks! I think each baby just grows a bit differently, they are human after all, no two are the same!
