The reason: Her new son Braydon – and the good wishes she and her family are receiving over his birth.
"Thanks so much for all the wonderful comments and emails," says Hart (whose current mood is listed as "Blessed").
The actress, 31, and her husband of five years, musician Mark Wilkerson, welcomed Braydon, their second child, on March 12.
"He was thankfully smaller (7 pounds, 3 ounces) than [big brother] Mason (9 pounds!), and I had a better experience this time around. I was able to do it completely natural, no drugs – and it was much shorter than Mason's birth (but by no means easy!)," says Hart.
Mason is 2 and, according to his mother, "a perfect big brother – he's loving, gives Brady lots of kisses and tries to helps me out."
Now, says the former Sabrina the Teenage Witch star, "we're home bonding and adjusting to this new miracle!"
One final note: "I've been getting a lot of requests for photos, but right now we're staying private and keeping some things just for us. Take my word for it – he's adorable and looks exactly like Mason did at birth!"
Even so, "We will be releasing photos soon though, so keep an eye out."
