Bedtime Woes

My 3-year-old's bedtime is fast becoming a nightmare for my husband and me! He was sleeping in his own bed, in his own room, and was perfectly happy with the arrangement, till we spent our vacation in Singapore for about 3 months. He was suddenly terrified of the dark, and refused to sleep by himself. Since countless threats, and hard spankings did not do any good, we decided our son was truly afraid of the dark, and so we caved in and took turns sleeping with him in his room, naively thinking everything would revert itself to normal when we got back home after our vacation.

When we got home, the fear of the dark followed our son home. He refused to sleep in his bed, in his own room, like he used to do for almost 3 years. He would scream, and cry hysterically, when we left his room! No amount of threats or harsh spankings would "calm" him down.

We're not seeing any light at the end of the tunnel right now!
