Your doing great dad. I love cooking too. I don't know how I will navigate the horrors of a cell phone, my guess is they will get them sooner than they need them.

At that point it's up to the character of your children.
Free will is and should be maintained. You just do your best and see if they were sponges and cam navigate according to the coordinates you instilled in them.
Intervene where necessary, within reason.
My kids got them at 14. Prior to that they had the Fire Tablets, that shut off to all but reading, after a set time.
When they are with me, their phones charge, in a central location, in the family room, before bedtime.
This is great information thank you. No phones into the night seems very good
