I'm thinking about getting a small trampoline with a bar for my daughter. We would keep it in the living room area. For those with a similar set up. Do you supervise every second the child is on the trampolin. I'm scared that they will fall if I'm not directly supervising. I spend all day with them, but occasionally will go upstairs to put in a load of laundry or do stuff in the kitchen while they play in the living room. I have 2.5 year old twins.
