A Year Gone By

The birthday girl will be one in 3 days and I can't believe it! I have been totally consumed with the party I've been planning and today was the first time I sat back and thought "this time last year I was beyond pregnant" now a whole year has passed.
I'm not sure how I feel about that. Don't get me wrong, I am more then excited at my little girl growing up, but how can I not be a little sad at the same time? She is 1 now and that means my son will be 3. You really start to realize how fast time goes by once you have kids and have something actually in your face saying "it's been a year, it's been 10 years, it's been 16, 20, 50 years!" With time moving so fast, it's hard to not feel like you could have done more in that time frame. Like maybe you failed this year. Maybe life should be a lot different then it was a year ago. For me, things are the same. Outside of the fact that I am not pregnant, my life hasn't changed much, if at all.
As I said before, I'm not sure how I feel about that. Being a parent seems to make time move so much faster then it used to, I don't think it's something that anyone can get used to, but it shows that you have to make the most of even the smallest things because they will all be gone too soon.
