not too much of an appetite after baby?

I had my son 9 days ago and since he's been born my appetite is a lot different then it used to be! I forget to eat meals at times and I look at the clock and notice the time and am surprised because honestly I used to always be hungry lol. Is anyone else feeling like this? I am happy that I've already lost 24 pounds of my pregnancy weight in 9 days! 16 of that was the baby and placenta and such of course.
