Here's what I'd do. Using the polygonal lasso tool ...
I'd select the area behind her head tight to the hair but leaving plenty of room around objects (remote/pacifier). I'd then feather the selection (select>modify>feather) by 1 pixel just to soften the hair edge ... hair can be tricky.
Then I'd use the clone stamp with a soft brush to pick up adjacent tones of the upholstery to "erase" the items within the selection.
As for the baby carrier (that's what they call those things) I'd just crop it out. That much couch really isn't important to the image.
My $.02 ... keep the change
