She scales the side of the cot and gets in - i stood at the door one night to see how she was doing it. Short of smacking her (which i don't do anyway for any other reasons) i am at a loss. Usually they both are in their own beds and talk and laugh then go to sleep. Yes - i would like her to stay in her bed.
DS is 1 and DD 3.5. I'm surprised she doesn't try to get in his cot, I'm hoping she doesn't figure it out because it's something I imagine shed love to do! DD is a climber but I can't imagine how she could get into either of our cots if it wasn't next to the bed. Were using an arms reach bassinet/cot now but used a Boori.

Is there any way you could put a bumper or even attach some wood to the outside of the cot to prevent the climbing?
