That's pretty much the way my folks raised their 5 kids when we mis-behaved, good thing I was a quick learner, didn't have to slap me too many times before I figured it out!!!!!!!!!
I'm sure our house had lead-base paint (built around 1950), but, I don't remember any of us kids chewing on the wood work, I guess my folks kept us well fed, so we wouldn't eat the house...
But they did use the roach poison that the exterminator would put in bottle caps and put around the house....I'm told it looked just like peanut butter and tasted close to it, I don't remember,I was only 2 years old when mom found me in the closet eating it, brought me to the hospital and as a precaution the doc went ahead and pumped my stomach, but said it probably wouldn't have done me any harm.......
I still use that episode as an excuse for the way I am today, getting good mileage out of that one!!!!!!!!!!!!!!
