I have a travel pass and so am able to travel for free, I have to pay for my daughter but there are times when there are matches on and the trains can be full so I would love to be able to book a child seat on the train. I have never been able to do this which means that I cannot reserve a seat for her as a child, I would also love to be able to reserve a seat for myself, even if it means having to pay a few euro for this service.
