At that age, babies get things to make MOM's life easier!!! Diapers, formula, carseats, maybe some outfits and a couple of toys, but you are the one who will have to open everything. He will not remember.
It's a great time to start a tradition or two also. Every year since my oldest was born, we buy a special ornament for the tree commemorating special things from the year.
And, just to share beyond, if your little guy gets fussy after the big day, it's most likely because he has been passed around and held so much. He may be a little sore.
