Congrats on #2. I felt the SAME way when I was carrying my second. I swear I thought he was going to fall out sometimes. Lol. Things are probably a little stretched out from the first one, I guess. As the pregnancy went on and he moved around and laid differntly, I lost that feeling.
And having two is so much fun (and work). My son (Jacob) was 26 months when his little brother (Ryan) came. They are now 3 and 10 months and it's just awesome to see them interact. They absolutely adore each other and we could see Ryan get excited at the sound of his brother at a very young age.
