My nephew was a toddler, we were having hot wings at my grams, and someone (this was back before we made our own sauces) left a bottle of tabasco with the lid off, on an end table in the livingroom... i forget the occasion, it was before my gram passed, so it was probably just an excuse to spend more time with her... any how, we were watching tv, eating hot wings, and all of a sudden someone see's something out of the corner of their eye, and realizes my nephew had grabbed the open bottle of tabasco and was sucking it down.
he handled it like a champ - both the bottle being taken away, and the resulting burn. no crying, and didn't seem to have any trouble the following day either (i was told).
Now he's 4, and his grandma spoils him rotten... he is afraid of hot peppers. He'll eat jalapenos though, if i just pinch a little off the bottom... But if his grandma is around and suggests it might be too hot, he cries and wants nothing to do with the pepper.
