Hello, I'm after some advice. My 3 year old little boy was at nursery the other day and was trying to climb a tree in the garden. They let little ones who can climb do it but won't let the ones that can't climb. As a result of him attempting to climb the tree he fell and has a spiral fracture on his right leg. He is in a full leg cast. I have spoken to the nursery and I believe it was an accident. My older children also attended this nursery and have had no problems. All of my friends believe I should sue the nursery for negligence but the thought never crossed my mind. It makes me feel an inadequate parent because I should be protecting my child but I don't believe there was anything malicious about his accident. They are adamant I should take this further. Who's right?
