I am pregnant with my third boy, my oldest one is almost 4 yrs old so I'm thinking about the same thing!
I do want to recommend an I Spy Bag (I make and sell them online). They're super fun for kids, and would be a great idea to give it to him if he's ever going to be in the hospital waiting room to keep him quietly entertained. I can custom make one for him, I can even put the letters of his name in the bag. Here is the link to the I Spy Bags in my store:
