Thanks ladies. We've already done very mild curry, but one of my baby food books advises not to feed chillis at all. That said, I've got three baby food books and all of 'em give conflicting advice at some point!
I'll experiment with a tiny bit of red chilli (enough for taste, but not enough for proper heat iykwim). And some milk on the side. Mimi, that's a really good idea - thanks!
