If you are staying in the same stateroom as your child, I would consider booking a room near a public space and bringing a baby monitor. That way, neither one of you have to sit in a darkened stateroom and you have a little freedom to read a book, play a game, have a drink, etc., but still be within steps of your stateroom. When staying on Freedom class ships (Freedom, Liberty), we've booked a midship balcony cabin near the library/loyalty desk/computer sitting areas that overlook the promenade. When sailing on an Oasis class ship (Oasis, Allure, Harmony, Symphony), we've booked a midship Central Park balcony stateroom on deck 10, and then sat in Central Park on deck 8. We've even found that the monitor will even reach to certain areas of the Promenade (i.e., outside of Boleros/near Starbucks Kiosk) from our Central Park Balcony Stateroom. I assume you could do the same thing if you have a Boardwalk balcony stateroom and wanted to sit somewhere on the Boardwalk. In terms of distance, it's really no different from having your child sleeping at one end of a two story house, and you taking the monitor with you outside while you wash your car. If your child wakes and needs comforting, you are no more than about 90 seconds or so away at any given time.
