For toddlers this young, Margaritaville is the move—it's explicitly built for the 2-4 crowd, which means shorter distances to amenities and staff who get the chaos. Meliá Nassau works too if you want the all-inclusive lock (no bill shock at dinner). Skip the bigger water-park resorts like Atlantis and Grand Hyatt for now; your kids are too little to log hours at pools and clubs, and you'll burn out hauling three toddlers around 1,000 acres. Bahamas beaches are gorgeous, but with this age spread, simpler footprints and strong toddler infrastructure beat resort sprawl.
