While pacing in the dark to get DC2 to sleep, it occurred to me that he and DC1 (2 years old) aren't scared of the dark. I definitely was at that age and remember being 18 months old and scared of it (still am a little).
Do you think that it could be linked to being left in the dark when little by parents? Could it be an innate, primal fear from when humans were vulnerable to predators, if so then why does everyone not feel scared?
I was left but have never left either DC, I have video monitoring and as soon as I see DC2 stir I head in to cuddle him back to sleep. If I haven't been able to go immediately then he just lays there calmly playing with his hands. DC1 doesn't need this as he is a great sleeper now.
Just idle curiosity, I don't fancy starting a bunfight about sleep training but I'd love to know your answers.
