I'm not sure how long past dd you are, but like the other's said maybe you're just past it and are moving on. Either way, I'm very happy for you because whether or not it's blocking out emotions or being over emotions, it's better for you to not be miserable every second of every day.
Whatever it is that's causing this, I have no doubt you'll work your way through it. You're a strong, smart woman, and you're being a great mother to that cute little baby. Lots of love and support~
