Abnormal Walking (including tippy-toe walking)

All children begin walking in their own individual fashion.  Many abnormal walking patterns can be ironically normal, as long as they resolve in a reasonable amount of time.

The most common abnormalities are in-toeing (or pigeon-toed walking) and tippy-toe walking.  Both can be completely normal phases of walking or they can be signs of a more significant malalignment or muscle tightness.
If you are concerned at all make an appointment to see your podiatrist, even if only for peace of mind.
