Never get the train anymore, first time today in about 10 yrs got train to take DS to London. Train home was really really busy people standing in all the aisles as well as the doorways. We sat DS who is 5 on our knee as I thought that was the done thing when train busy. Family near us had two kids, one about the same age as DS, one slightly older maybe 6 or 7, kids had a seat each for the entire journey. I know its not comfortable to have kids on your knee for long time but its more comfortable than having to stand, there was 4 adults in there party so they could have taken the knee sitting in turns or even made the kids squeeze onto one seat to free one up.
