I have a really deep-rooted fear of the dark after being locked in a cavity beneath my parents' house as a punishment a number of times as a child (not a punishment given to me by my parents but by someone else who would often look after us).
I'm now 35 and I still struggle to sleep with the light off. I can sometimes sleep with a nightlight on if it's bright enough. This has been an issue for many of my partners over the years and I have had arguments with exes about it.
I now have a baby and my DP is worried about not sleeping with her in darkness as he thinks it isn't good for her. I co-sleep with her and have tried but i always end up switching the light back on (or at least putting on the night light). Am I causing her damage by not sleeping in total darkness with her?
