I put this in the doorway to my 3 year old’s room and then walked away. It’s been 4 days now and he hasn’t tried to leave the room. Heck, he hasn’t even cried!! Every so often I put a bowl of water in the floor and some sandwiches and I see him rocking himself gently to sleep under his mattress, all tucked in. This is SOOOO much better than leaving him in the kennel – and guests are much less judgmental. You should get your today!
