I was just about to post the exact same thing!

I tried giving some to DS1 when he was a baby and it touched his cheek and went bright red straight away.
Now 5 years later I had totally forgotten about that incident and went to give it to DD and most went in her mouth and some dribbled down her cheek and again bright red!
The colour got darker and the faded to nothing.

So I would like to know if it does anything also? Doesn't sound right does it!
