The Duggars are obviously famous for their ability/willingness to have a whole lot of children, but they’re just as well known for their hands-on approach to parenting.

Each of the Duggar kids was homeschooled, and these days, they’re carrying that tradition on with their own kids.

Now, fans are wondering if the mother of two Jessa Duggar is up to the task of educating her sons herself.

That’s a video of 2-year-old Spurgeon that Jessa posted on Instagram earlier this week.

“One of the cousins must’ve been giving him lessons,” she captioned the clip.

Like everything the Duggars do, the photo has been scrutinized by fans, many of whom don’t like what they see.

Spurgeon is obviously doing an impressive job of identifying his shapes, but some of Jessa’s fans have taken issue with the lessons being taught to the boy.

The cousins that Jessa is referring to must be Josh Duggar’s kids, as none of the other children in the family are old enough for such an advanced lesson.

Josh’s oldest is 7, and fans have pointed out that he could use some work on his spelling and shape recognition.

(Like we said, this crowd loves to complain.)

“Impressed with Spurgeon’s memory!  But you might want to review octagons and hexagons with his big cousin,” tweeted one fan.

Others commented that there are several misspellings on the board, and none of the adults have stepped in to point out the errors.

“Shaps? Interesting that it has NOT been corrected. Do they believe it is correct?” commented one Instagram user.

Obviously, this is nit-picking of the highest order, and fans shouldn’t be so critical of a couple of kids playing school.

At the same time, however, since the Duggars homeschool their kids, it is their responsibility to ensure they’re not being misinformed.

Most parents could just laugh and walk away from a scene like the one in Jessa’s video, knowing their kids would eventually learn their shapes and spelling in school.

Unfortunately, Jessa doesn’t have that luxury.

Homeschooling is a massive responsibility, and since it’s rare to see a member of the Duggar family reading a book that’s not the Bible, fans will always wonder if the parents are doing right by their kids in keeping them out of school.

Of course, within her family, Jessa’s teaching abilities are being universally praised:

“Spurgeon went 7 for 7. My best was 5 for 7. He’s a genius!” tweeted Jinger’s husband, Jeremy Vuolo.

Clearly, Jeremy is kidding … we think.
