Where in the world is Mason Duggar?! The newest Duggar baby doesn't get a fraction of the attention that his cousins do, since his parents Josh Duggar and Anna Duggar don't use social media, but he's still a beloved part of the family!

The little guy made a rare appearance in a New Year's Eve post on the Duggar family Facebook page, being lovingly held by his mom alongside his four siblings and dad Josh. The post said, "3 new grandbabies, 2 beautiful weddings, 1 new son-in-law, 1 new daughter-in-law, birthdays, anniversaries, and a whole lot of love! The Lord has been good to us in 2017! We can’t wait to see what 2018 holds!!" Get to know the adorable little guy by scrolling through the facts below!

When is Mason Duggar's birthday?

The Duggars announced little Mason's birth on Sept. 12, with an absolutely adorable photo of the baby boy. "Both he and Anna are doing well," wrote Josh on the family blog. "He arrived today without complication and we already adore him. The entire family is ecstatic over the arrival of another beautiful blessing. We want to thank everyone for your prayers, kind words and well wishes. We appreciate it much more than we could ever express. We pray God blesses each of you with an abundance of the kindness you’ve shown us.”

However, it wasn't an easy road to get there! “Her water broke Monday morning early and she labored all day before having Mason at 1:22 a.m. Tuesday,” a rep told Us Weekly. Anna later opened up about how long and hard the labor was, saying “It was a long labor, but complication free and I feel really great. It’s a blessing to have so much help from our moms and family members. Our other little ones adore Mason and want to hold him all the time!”

As of now, Mason is still the youngest Duggar, but Joy-Anna Forsyth looks about ready to pop (and some fans think she aready has) so that will change soon!

Is Mason Duggar being blanket trained?

The Duggars famously use the child-rearing method called blanket training, where parents place their babies on a small blanket, and then snap a ruler at them if they try to crawl off of it. The idea is to train the kids to be very obedient when they're young, but it's also controversial for obvious reasons. Josh and Anna have not admitted to using this method, but it's likely that they will.
