Well, the 18 week photo doesn't look too different from the 16 week one, but it'll be fun to keep track. I can tell the difference, if no one else can see it! We did actually take a 17 week picture as well, but it didn't turn out very well; for some reason the autofocus didn't work.
The last couple weeks have been good, I'm still feeling good and we are slowly starting to set some stuff up. I think I've started feeling the baby move! Just tiny little pokes, but definitely getting more noticeable. :-) It's pretty amazing. I'm really excited to feel it more strongly, especially for when Nick can feel it too.
