Sure! My little cousins had one and the one who was only two at the time LOVED it. Especially if she enjoys singing, she’ll like it. Does it record as well?
Do you remember when the hand held recorder from the Home Alone movie became popular? With the voice warp? And they sold it in the kids’ section as a kids’ toy? I got one for my birthday when I was around 7 and loved it and used it all the time… I know it’s not the same as a karaoke machine but similar concept. It may be something that might be more for older kids, but I also know kids who like to sing along and hear themselves sing from early on and would love something like that.
