The actress, who had her son via surrogate, first introduced the world to him back in August...

Now the 46-year-old has taken to instagram to post an updated photo of the "love of her life." Lookit the cheeky chops on the liddler!

Speaking in an interview with Today, the Sherlock actress said of motherhood: "Every day is just a miracle and a dream. Because everything is so different every day. You’re not even thinking about ‘Is it Monday or Tuesday’ or ‘What time is it?’ anymore, you’re just thinking about how he’s changed from minute to minute and his reactions - also, how you are and how you grow as a human being, being around another human being like that."

When asked if she'd start calling her son, "Rocky" she was quick to respond "I hope not."
