  "question": "Which add-ons must be bought in addition to the stroller's listed price?",
  "answer": "Silver Cross Wave 2023: Says seven modes come out of the box and up to 30 are possible with accessories, with no extra purchase needed for the base double setup. Snuggle Bugz describes the bassinet as sleep-safe approved for newborns and the main seat as suitable from 6 months to 55 lb; sources disagree on the separately sold tandem seat's limit, with Snuggle Bugz and the store listing saying 55 lb and the video review saying 44 lb.\nBugaboo Kangaroo Family System (PM007378; PV007712): The newborn can ride high in the bassinet only after buying the upper newborn adapter; the sibling sits lower for stability.\nSilver Cross Wave 2021: A second (tandem) seat and the toddler ride-on board are not included and must be bought separately.\nBugaboo Donkey 6: The blog advises measuring your trunk and any unusually narrow doorway or lift before buying, and pricing the full mono, duo or twin setup rather than the starting price.",
