The room temperature should be kept low, obviously. Synthetic sheets, and blankets lock in heat, as well as bed clothes. Switching to cotton sheets, and bed clothes can be very helpful, as well as a fan in the room to keep the air circulating. Other physical causes for night sweats include hormone imbalance, which in your case probably doesn't apply, an infection, especially brohnchitis, as well as acid reflux. If it is both you and your daughter, It would suggest that the room is just to warm.
