Big Brother Gift

Maura
So my 7 year old is BEYOND excited about having a baby brother, but I can tell deep down he's scared he's going to be pushed aside/forgotten about.  He's been the center of my world for 8 years so it will be a change for all of us of course.  I want to have a special gift "from his brother" for when he comes to the hospital right after he's born to see him.  Has anyone done this or does anyone have ideas on what to put in it so he feels involved, important, and like the huge part of his brothers life he will definitely be?
