I personally have been eating raw cookie dough for more than 60 years, and have NEVER
gotten sick from it! also raw cake batter! I am not recommending that you feed it to your kids, but on the other hand, none of the kids I knew/know who eat the "regular" kind of cookie dough have ever gotten sick, either.
Use your own judgment, and above all, have FUN!
Baking should be fun.
