What Is It Like Being An Autistic Mom?

I have an older sister who is autistic and married. She has two cats and gets sensory overload when they meow nonstop (very sensitive to loud noises), sensitive to many textures, sensitive to temperature, very emotional, loves her alone time, and has a routine life. My Mom wants my sister to get pregnant and deliver at least 2 kids. My Mom thinks that my sister can handle 2 kids, and said that she will take care of them fully if my sister doesn't want them.

To the autistic Moms with kids out there or people who know autistic Moms with kids, what was your experience like raising kids?
