I am so glad you saw your tummy move, it is special isnt it, I actually remember thinking along the same lines as you, I was quite worried that I had not felt alot of movement etc and got a little panicy, but at about 30 weeks I started feeling it a bit and by 33 weeks I felt it alot from outside. so yeah try not to stress to much I think each person is different,

mumtobe that is so sweet of your DH to do that I had a real 'awwwwwww' moment LOL
