How old are you all guys??

I was reading this post and I am amazed on how many of you had twins after twins knowing there was a chance.

I always wanted three kids, so having twins as my first at 35 yo was a good thing for that hahaha but even when id love to go for the third, I will be almost 40 and it honestly makes me think things.

How old were when you had your nultiples and singletons? Or how old are you know if you are pregnant :)
