A mum has sparked a fierce debate after asking parents whether or not her 11-year-old son is too young to travel alone on a train, with only a younger child for a companion.
The parent explained she's trying to work out the logistics of a plan - and if it goes ahead, the pair will travel alone without an adult.
However, she was keen to stress the kids would be supervised by grown-ups at either end of the journey.
In the controversial post to Mumsnet, she questioned if she was being unreasonable "to think 11 is not too young to travel on a train alone".

"Please settle a debate! Happy to hear all opinions," she wrote, introducing her conundrum.
"Is 11 years old, starting year seven in September, too young to take a one hour train journey, without parents but with a slightly younger child?" the mum asked. "Put on at one end by an adult and met at the other end by an adult, with a phone and data, and train staff informed? No behavioural problems or SEN."
But several commenters felt they could not fairly answer the question with the information given.
"More context needed I think. Responsible for younger child - no. Ok to do journey on own - not used to train, few other passengers, few stops, unfamiliar journey - probably not quite yet - too vulnerable to deal with weirdos. Train to school full of other kids on the same journey with lots of stops - should be fine," read one reply.
Echoing a similar sentiment, someone else said: "An 11 year old should not be responsible for a younger child on a train."
A third wrote: "Most 11 year olds this would be fine, loads of children where I live do this at younger. Looking after another child, not sure about this at all."
Meanwhile, a different person commented: "How old is the younger child - do you mean two 11-year-olds getting the train together? 11 and 10 I'd think they'd be OK. 11 and 6 no I wouldn't."
The mum responded: "Do you think that an 11 year old is safer alone than with a younger child? Other child only one year younger," which in turn prompted further debate.
"Are the two kids likely to argue? Having an 11 year old responsible for a 10 year old is not ok," one parent thought. Another advised: "11 and 10 I'd tell them to stick together and be responsible for each other. Not having all the responsibility on the 11 year old's shoulders."
