A full attention is given to the children. For the small ones, a nursery is at your disposal: tables, 4 beds, toilets, etc. When time is coming to give the bottle, babies will be in a quiet area, not so far from the event.
Children have a lot of space to move and spend energy in the park where they could play swing or climb rocks. During the evening, when adults are eating and dancing, children could spend time in the gaming room at the first floor to practice baby-foot or in front of cartoons (LCD screen).
Obviously, we put a list of referenced baby-sitters at your disposal if needed.
