Narrative:

During descent we hit what I clarify as severe turbulence. Passengers and flight attendants had been warned about the possibility of moderate turbulence forecasts before the descent. I told the flight attendants that there was going to possibly be turbulence in the terminal area approximately 4 hours before arrival. With that warning in mind; they started their final service early so that they would be prepared to have the cabin ready for landing prior to descent. ATIS reported moderate turbulence from FL200 to approximately 11;000 ft MSL. The flight attendants had finished their service and prepared the cabin for landing approximately 45 minutes to an hour prior to landing. Numerous PA's were made by me; the captain; and the flight attendants that the expected turbulence was in the terminal area and that service would be stopped early. The expected turbulence was encountered from approximately FL300 to 11;000 ft to 6000 ft; light turbulence was encountered. During the descent the flight attendants advised us that they had one male passenger that was incapacitated and would not respond. We advised company operations of the passenger medical problem and requested paramedics meet the flight. We requested runway xxl due to windshear reports; crosswind components and wet runway conditions. We encountered severe turbulence for 2-3 seconds approximately 30 NM from the airport on an approximate westerly heading on radar vectors for a right turn in to runway xxl at 5000 or 6000 ft MSL. Flight attendants were in their seats but called the cockpit and advised us that it appeared that a baby had flown out of the mother's arms and had possible injuries and an adult male passenger had flown out of his seat and landed on a lady passenger. We declared a medical emergency and landed without further incident. Paramedics met the flight.

We advised Company operations of the passenger medical problem and requested paramedics meet the flight. We requested Runway XXL due to windshear reports; crosswind components and wet runway conditions. We encountered severe turbulence for 2-3 seconds approximately 30 NM from the airport on an approximate westerly heading on radar vectors for a right turn in to Runway XXL at 5000 or 6000 FT MSL. Flight attendants were in their seats but called the cockpit and advised us that it appeared that a baby had flown out of the mother's arms and had possible injuries and an adult male passenger had flown out of his seat and landed on a lady passenger.
