My 3 year old is intoeing how long till she grows out of it?

Usually outgrow: Vast majority of children younger than 8 years old intoeing will almost always correct itself without the use of casts, braces, surgery, or any special treatment. A child whose intoeing is associated with pain, swelling, or a limp should be evaluated by an orthopaedic surgeon.

Normal: In-toeing is common and usually not a problem. Most will outgrow it. It does not interfere with motor development. An interesting fact is about 50% of elite, competitive runners in-toe. So don't worry about it.
