I'm not yet 4 1/2 months into my pregnancy. However, I'm showing quite well, I too easily tire out, I get sore in so many places after a day of work (or after standing for a while), my belly hurts when placing Simon in the crib, etc.
On the other hand...I can feel him moving around a lot. I love that part! It doesn't hurt to have him move, or sit up top like he does. I love knowing that he's growing and doing well.
Also, I think we've picked a name...and no, I won't tell you what it is. We have to have ONE secret!
