I am actually touching my belly a lot now. I wasn't so much in the beginning. DH was a lot more, and he was talking to the baby early on. But lately I can't seem to keep my hands off my belly. Its roundness is so new and cute (I know I prob won't have this enthusiasm in a few months). When I sit and work at my desk, I can feel the little guy moving around and I am always putting my hand on my belly to feel it. It just feels good to rub my belly regularly-sometimes give it a good massage.
I had my 20 wk u/s on Tuesday, and the tech did some 3D images (some turned out really good of his face), and I keep looking at them wondering how I supposed to wait another 20 weeks to hold this little guy? So for now, I can rub my belly when I think about him.
I love that your other children are getting so excited for the new baby, even if they don't fully understand what's going on. Very cute!
