What are some fun musical instruments for toddlers?
user
How old is the child, and what are some things they’re interested in?  Some suggestions:

--kid’s harmonica
--cassette player
--kazoo
--twinkling keys
--record player
--animal calls and sounds (e.g. parrot, fish)
--various types of shakers
assistant
Okay, those are cute. The child is three.

Then I would suggest any of these:

--piano
--guitar
--violin
--mandolin
--maracas
--bottle-like percussion instrument (e.g. djembe)
assistant
Which would be a good beginner one just to make noise?

Any of these would be a good “first instrument” that you can build on over time:

--piano
--guitar
--violin
--mandolin
--tambourine
--drum (any type)

It depends on the child’s interests.  Are they interested in science and medicine?  Then maybe the maracas.  Are they interested in animals?  Then maybe the djembe or the bottle-like percussion instrument.  Or maybe you can play with the child and try a few different instruments
