An interesting question. When it comes to a child, no - they may not speak the truth, but it's not a lie - it's a reflection of their perception and/or understanding of a situation. As they get older, then a lie becomes a lie when it's a deliberate untruth told rather than a different understanding of the same situation. For teens and adults, unless there's a mental disorder, then I would say that a lie is a lie. Severity doesn't make something a lie or not - it's more a judgment call on how severe the lie is based on who/what it affects and how much and by who's standards.
