“Behind every great kid is a mom who’s pretty sure she’s screwing it all up” (or “Behind every great kid is a parent who’s pretty sure they’re screwing it all up”) is a jocular parenting saying that has been printed on many images. “Behind every great kid is a great family” was printed in a 1995 book.
 
“A line from Hallmark - ‘Behind every great kid is a mom who’s pretty sure she’s screwing it up.’  Happy Mother’s Day to all the great moms!” was posted on Twitter by Jennifer C. on May 9, 2010. The saying probably originated with this Hallmark image.
 
“Behind every great kid is a parent who’s pretty sure they’re screwing it up” was posted on Twitter by Helen Marie Lewis on April 1, 2013. This saying also probably originated from an image.

I recently saw a quote on Facebook that said, “Behind every great kid is a mom who’s pretty sure she’s screwing up.” It resonated deep in my bones.
