Keep toy instruments around the house to allow your child to experiment. You can get toy drums, pianos, guitars, recorders... just about anything. This is a good way to see, not only if your child is interested in music and learning to play an instrument, but also which instrument -- or type of instrument he or she is interested in. As your child's interest develops, you can move beyond toys.
If your gifted child seems interested in a toy keyboard, you can move from a toy one to an inexpensive real one. And you don't need to start right away with lessons either. However, you don't want to wait too long for lessons. Learning to read music, positioning, and correct posture and are all important parts of playing a particular instrument.
Remember, the more musical toys you have available for your child to play with, the better the chances that your child will find one he or she loves.
