how to deal with haters?

ADK83

my sister-in-law really hates babies, and says things like "ew" and "i don't want to touch it" around other people's babies (she's in her mid 20s). can anybody think of a way to approach this so that she at least doesn't make those comments to me when we have a child? perhaps i should just ignore it, but i think it would really upset me to have my child treated that way.

thanks!
