What would you think?

For a laugh me and my mum saw a psychic today. When I asked if I was going to have anymore children she just said possibly. When my mum had her reading done she was told that if me and my husband have another child then she sees it as being disabled or with mental health issues?  A lot of the things she told me were correct and I just kept thinking how does she know this?! Now I can't get her comment out of my head! Wish I'd never met her....
