On her Instagram account, Jill, 26, directed fans to the video on the Dillard Family website.
She captioned it, referring to her mother Michelle, "My Mama taught me this trick about infant car seats! I use it when I know we are gonna be in tight spaces and I don't wanna pull out the big stroller. Super easy!"
In the clip, filmed at the Dillards' home, Jill commented, "I don't know where my mom learned it from but I do this all the time whenever I know I'm going to be in a tight space like at church or somewhere. Instead of taking the big single stroller, I just take my umbrella stroller and put the car seat on it and it makes for a nice small single stroller."
However, when the former Counting On star demonstrated the move, nesting the car seat on top of the stroller, it looked unstable.
After watching the video, a follower on Jill's Instagram wrote, "This is SO UNSAFE."
Another hater weighed in, "So if space is tight for a stroller, why can't you just hold or wear your baby? I don't understand. Or why can't you just put your baby in the umbrella stroller instead of stupidly hanging the heavy car seat in the little stroller with baby in it? I just don't understand the reasoning behind this stupid idea your mom taught you."
And yet another Jill Instagram watcher opined, "I don't agree with what she's doing bc it's extremely dangerous. And I definitely wouldn't do it. I think the point though is she shouldn't post it online as a hack for other moms who may not realize how dangerous it is to see and try."
As Radar has reported, Jill and Derick have been ripped for putting their kids in danger by doing a mission trip in Central America.
Online critics have also blasted Jill for putting her then six-month-old second son, Samuel, on a dirty carpet!
This week, controversy swirled around disgraced husband Derick after he blasted gay TLC star Nate Berkus and his family.
The former Counting On dad is always getting into hot water with comments seen as intolerant. As Radar previously reported, TLC, the network that made the Duggar family famous, cut its ties with Derick after his social media posts about transgender star Jazz Jennings caused shock last year.
Now Jill, with oldest son Israel babbling in the background audio, is saying about her stroller wrangle, "This is super nice whenever you're in a hurry, you don't have a lot of space and you can't fit the big bulky stroller in your car, little tip, trick from my mom that I use all the time."
