Yes, some children have naturally flexible joints, which is often referred to as being "double-jointed" or "hypermobility." This increased flexibility is due to looser ligaments and tendons around the joints. In many cases, joint hypermobility is harmless and can even diminish as children grow older. However, if it causes pain or frequent joint injuries, it might be part of a joint hypermobility syndrome and may require medical attention.
