I really wish there was that magic 8ball. KWIM?
A wise friend of mine with two kids on the spectrum once said to me,"Statistics don't mean much once it happens to you."
We have twins. Baby A is my ASD child. Baby B is kind of NT, not spectrum, but language disordered (apraxia, et al). I'd love to have another baby, hopefully just one, LOL, but I get scared.
I say you have to just pray (if you're of that persuasion) or trust your instincts.
God bless you. ((hugs)) And y'all will be in my prayers.
