I agree, he does go to sleep with the night light on dimmed down. We respond to his initial cry, assure him we understand his feelings but there is nothing to be afraid of, offer love and support and then return to our bed. He wakes in the morning happy and cheerful. As any parent, I just wanted to make sure we weren't causing any additional issues or emotional damage.
We are trying to keep he and his twin sister sleeping in their respective rooms but it has been difficult with the tantrums being so convincing. His sister has always slept well in her own room.
