Ryan Hadley fell down in the playground and went over on his ankle. His mother, Alison, brought him in to the Queen Elizabeth A&E "because it was easier."
She told ITV News that she might have taken her son to their GP but felt that they were likely to be sent on to A&E in any case: "We might as well cut out the middleman and come straight in."
Mrs Hadley said that she decided not to take 9-year-old Ryan to the Birmingham Children's Hospital because they hoped the wait would be less here.
She said: "I went there with my other son recently and waited for three hours - we're not going through that again."
A&E departments across the country are having what some people call "a challenging" time and others say is a full-blown crisis.
Queen Elizabeth Hospital Birmingham is a major trauma centre treating the most severely injured casualties from across the Midlands.
