Hey Di, I traded to care for my grandkids this week, instead of my Dad. So got to take a looksie at the ingredients in the formula....yep, calcium hydroxide.
I don't care for hornet nests but I do like people to see with their own eyes what calcium hydroxide is really like. If babies grow up using the stuff without ill affect, why would we not realize that in small, diluted amounts, it's very safe to use. It's calcium....good enough for babies to benefit from.
Heck, even baking soda has warning signs about ingesting or getting it in your eyes. Where are all the bells and whistles going off about that?
