How much information do you get from your teens where they are and what they are up to with their friends?
DD2 has started going out more since starting year 10 in September; she is nearly 15, sometimes friend houses, shops, general exploring. I give her all the warnings of course, keep in touch, have location sharing, ask for some information.
It does cause me some anxiety though as we live in London: sometimes she is exploring further afield. Didn’t have that problem with DD1 as she is more of a homee one, mostly went to friends houses, sometimes shops, doesn’t like big parties.
