"I am just very aware of not letting my running interfere with everyone else"
Why should you have to ensure that your running doesn't interfere with everyone else? You have a right to a life too!
Your husband and kids are big enough to look out for themselves occasionally, and surely your kids should be learning how to feed themselves?
Anyway, I would think you'd be as safe at 6.00 am as at 6.00 pm, so you should choose which you prefer.
