My boys have both like spicy foods from the beginning - certainly by 12 months both were eating medium - hot curries from our local Indian restaurant, and the same home cooked meals as us, including chili curries, chili in pasta, etc. It is so much easier having the whole family eating the same things.

I have heard that if you eat spicy foods during pg and bfing that kids are more likely to eat them at a young age. I'm not sure if it's true or not, but it might explain why my boys are so good with spice.
