Inquiry: Does anyone have an autistic child, and then went on to have a neurotypical child?

Or did you have an autistic child as well. I'm reading its 7x more likely to have another child who is autistic. I'm concerned I won't be able to handle it if I have two autistic children. My first one already takes up literally every single second of my time, unless he's at school.

Edit: THANK YOU to everyone who responded and for sharing yourselves with me. Thank you for the advice as well. I love my son but it's just tough. But I always wanted a sibling for him and it's been a difficult decision. THANK YOU.
