It sounds like you received Swiss Travel Passes for 2 adults, which is correct. A 4 year old does not require any pass or ticket, so you are good to go. Only children between 6 and 15 need a free Swiss Family Card, but I guess they did not send you one because you don't need it. You do need passports on you at all times so you can prove you're the parents of the child, and his birth date.
It's weekend now and Monday is a holiday, so they may not get back to you until Tuesday. All of this sounds ok though. In case of any doubt you can show your passes at any staffed train station in Switzerland to verify it's fine.
Enjoy your trip!
