There are many challenges that come with raising 20 children.
You have to feed and clothe a small army, you have to yell out the right name when you're angry, which is often a challenge even for parents with regular-sized families...
... and of course, you have to remember 20 different birthdays.
Lately, that last task has proven a considerable challenge for Jim Bob and Michelle Duggar.
Yes, despite their claims of being the planet's foremost super parents, the Duggars have been forgetting birthdays lately.
But don't worry, they've been doing their damnedest to cover their tracks.
Shortly thereafter, Joseph Duggar turned 23, and his parents obviously forgot about his big day entirely.
They compensated by posting a video with a Jay Leno impersonator they'd just happened to run into, which sounds like something only the drunkest of stepdads would attempt to get away with.
Needless to say, the Duggars took quite a bit of flak, for their recent lapses in memory.
So it should come as no surprise that they've taken steps to ensure that no such errors occur again.
After all, forgetting your kids' birthdays is one thing - being called out as anything other than models of perfect parenting is quite another.
Many fans of the family aren't even aware of this, but back in 2016, the Duggars adopted a 20th child.
His name is Tyler Duggar and he celebrated his 10th birthday over the weekend.
Newly self-conscious about assuring the world that they remember the dates all their kids were born, the Duggars took to social media to pay tribute to Tyler.
The Duggars posted the above photo on Facebook, along with a caption praising the newest addition to their massive brood:
"Happy 10th birthday Tyler, a whole decade now!" Michelle and Jim Bob wrote.
"You are such a joy and a delight! We are so thankful for you! We wish you a happy birthday and look forward to another great year!!"
Comments on the post served as a reminder that many fans were not aware of Tyler's existence:
"Happy Birthday young man...Tyler. But, who is Tyler? All Duggar names start with a J," one fan wrote.
"Who is Tyler? I thought all there [sic] kids' names started with a J? Did they adopt?" another remarked.
So it looks like the Duggars haven't been very good about celebrating all things Tyler on social media.
But hey, at least they remembered his birthday!
