DD is 13 (nearly 14) & travelling 60 miles on her own by train
Last week was the first time & she was non-contactable for the whole 8 hours she was gone (phone battery died, no credit etc)
We explained that this week she must text at appropriate times (eg on train, on arrival etc). Ensured credit was on her phone & checked it was charged.
She hasn't; so next week one of us will travel with her as she obviously doesn't want to do this by herself (IMO).
That seems fair to me but is it OTT?
