When I was living at home, my mom had 2 or 3 night lights thoughout the house. I heard that this can cause night blindness. I was wondering if anyone else has night blindness from having night lights in their childhood? I do have night blindness since I was 14 years old.

Bah! A LavaLamp is the best nightlight for the child:-D...

We co-sleep with our young children which is alleviates some of the night time fears that young children face when sleeping alone and can lead to use of a night light.  An added benefit is that we are available to assist them if they need help navigating to the bathroom.  We also try to get up when the sun comes up and sleep when the sun goes down so that the transition to darkness is gradual for them.

I am a mother of three adult children who were raised with no nightlights. We did what was natural and didn't emphasize the need for a night light. I know my children thought they wanted a night light because their friends had them but I taught them to allow their eyes to focus to the dark before getting up to walk. It happens naturaly and fear happens the same way. My children weren't necessarily afraid of the dark but what they may have heard or 'shouldn't' have seen - so I had to reiterate after a bad dream...what their fear really was. All too often we're inspired by great marketing to purchase them. Why spend the money? No side effects from sleeping in the dark. Respectfully, healthywithoutIT...
