I know lots of people will have taken their kids from when they were babies but what about everyone else? We just had a short (localish) trial run as we've been given a massive tent. Children are 5 and 2. The 5 year old had a ball but the 2 year old was a nightmare! I had to take her home on the first night as she was too wired and then hysterical to sleep. Both kids exhausted the following day. What are we doing wrong?
