My DD1 likes to go and play out the front in our cul-de-sac with her friends. The PFB mum in me says I ought to be standing out there with her. The common sense bit of me makes me want to stand inside with the other children in the warm, but looking out for her every two minutes. The practical I've-got-lots-of-other-things-to-do part of me makes me want to get on with my jobs, and ask her to come back to the house and knock to let me know she's ok every now and then.
So, what do others do? How long are you happy for your 7yo to be out of your sight for? What are your rules?
