what age could your child enter your locked home solo?
for our house it was age 5. We have an electronic lock on one of the doors that you can enter by code. She obviously never went into an empty house, but sometimes preferred to get into the house through that door instead of one of the unlocked doors that weren’t as conveniently located in the moment.
She is 13 now and still doesn’t carry a key since she can just enter with the keypad.
