If you head to Setup > Plans, you will land on an overview of all your children's bookings. You can make amendments from here and filter your bookings down, to view the ones you want to see.
You can use the filters on the left hand side to select:
1) Active plans
2) A particular room
3) A particular type e.g. full year plans, or term time plans
4) Plans with a particular booking on them e.g. an AM session, or a Lunch product
You are then able to choose to see plans of past, current and/or future children at your setting.
