LO is now over 7 weeks old, and I've been thinking more and more that I need to capture all of these "firsts" with baby, whether it's his first trip to the market or the first time he really smiled, that wasn't obviously gas. My mom has also been encouraging me to buy one, but I'm at a loss as to which one to get. I'm normally not very good at keeping up with these things, and didn't even get one to mark the pregnancy.
If you did manage to keep one, which one did you use?
