We used to do that as children also. With our kids we do not let them in our bed. We put them on a pallet next to the bed. This is not as cozy as their bed (or Ours). We then talk to them the next morning about If they stay in their own bed all night, we will have a popcorn & movie Party with them Friday night ( a reward). But, My parents just let us get in their bed and we always woke up in our own. Even if it was 2 times a night we always woke up in our own bed, which really made it not worth our while, so we quit getting in their bed. Also, when our oldest started doing this nightmare business, we started turning off the T.V. at least 45 minutes before bed and having her color instead.
