Sandra Bullock is organizing an outrageous festive-themed photoshoot for her son Louis this Christmas so she can show the embarrassing snaps to the tot when he's a teen.

The Blind Side star adopted little Louis from New Orleans, Louisiana last year and admits she's looking forward to spending the holiday season with her little boy.

Bullock insists her plans are verging on the "ridiculous" as she prepares to take plenty of pictures of Louis, which she can hand over when he's older to prove she was a "good mother" to him.

She tells Us Weekly, "I want the photo ops to be really great because he's not going to remember it, but he'll remember it by the photos and when he's 16 and says, 'I hate you - you're a horrible mother!' I'll go, 'Do you see this Christmas? Do you see that I got you that life-size lion? Shut up! Get in your room and do your homework. I was a good mother then.'"

But despite relishing her new role as a mum, the actress isn't sure she's ready to expand her family by having another child.

She explains, "I don't know (if I'll adopt again). I'm so blessed with what I have."
