I have even tried it myself.
It tastes fine. Not harsh as the adult version.
Regardless what kind of mouth wash it is I always add a bit of water to dilute it.
The bottle recommends the child to be at least 6 years old or older because they dont want the child swallowing it.
My daughter does not mind the taste.
She does NOT like mint flavoured so this is ideal for her to use.
What I really like about this bottle is that it is kids friendly.
Instructions written on the bottle: "remove cap and hold bottle upright. Fill to 10 ml line by squeezing the front and back (not the sides) of the bottle. Stop squeezing. Excess liquid will drain back into bottle. Pour out."
So the solution is squeeze out into the "cap" and then you pour it out into a cup to use.
That way, the child does not accidentally empty the whole bottle out when he/she tries to pour it into a cup.
My daughter really like Tinker Bell on the bottle.
I named it "Fairy Water" that will help clean her teeth.
Would I recommend this? Yes. It adds an extra step to help to protect their teeth.
Would I re-purchase it? Yes, if it is on sale.
