Teen Mom 2 star Kailyn Lowry is a mother of three children with her fourth child on the way.
She just shared a video in which she showers Lux, her youngest (born) child, with love.
But when a fan's praise of Lux insulted her longtime co-star Jenelle Evans' daughter, Ensley, Kail was there to shut it down.
"Are you the cutest boy?" Kailyn Lowry asks her two-year-old son, Lux in the video that we have included with this post.
He very correctly replies "Yes," smiling happily at his mother.
"You are?" she prompts, seeking confirmation.
Once again, Lux answers in the affirmative.
"Say cheese," Kailyn asks.
Look at this angel.
The son of Lowry and Chris Lopez - who's also the father of her soon-to-be fourth child - smiles, flashing his tiny little baby teeth.
"I love you!" she tells him, which he echoes back at her.
They both tell each other: "So much. SO much!"
For some reason, a Twitter user decided to do what trolls on Twitter do, and make childhood speech a competition, pitting two-year-old Lux against Jenelle Evans' youngest child.
"He talks 10 [times] better than Ensley, is clear, and actually comprehends," the reply reads, clearly insinuating that Jenelle is a bad mother or that Ensley is a failure or both.
Either way, it's ridiculous.
Notably, Lux and Ensley (above) were both born in 2017. Ensley is now three years old. But as far as Kail is concerned, that's where the comparisons should end.
"I’m sure she will get there," Kail told the commenter.
"All babies / kids learn at their own pace."
A gentle mic drop, but a mic drop just the same.
Kailyn is absolutely right about development.
Plenty of young children who are positively brilliant may not begin speaking until they are two years old.
Others may begin talking in individual words or even simple sentences before they are ten months old.
If you're from a family where most children tend to speak early, it can be strange to see a celebrity's one-year-old not talk yet.
But it's not abnormal.
"That’s so mature of you,” one person wrote regarding Kailyn's soft clap-back. “I love this. (And I’m not a fan of her - Jenelle)"
"BUT children are not at fault for ANY adult drama," the Lowry fan continued. "PERIOD! #Respect"
"[Kail] I will give you credit for this. I guess you showed a bit of maturity today. You get a [cookie]"
"This, by far, has been your best tweet."
Ensley is, arguably, at something of a disadvantage when it comes to development, albeit not for this reason.
Long before David Eason shot her dog, he and Jenelle were accused of both abusing and neglecting their kids.
Children speak and learn better with enrichment, love, and stimulation. It's hard to argue Dave Eason provides this.
An abusive household can have lifelong adverse effects - whatever your issues with Kail, her kids are not exposed to that.
Kail is pregnant with her fourth child; Lowry has seen Isaac, Lincoln, and now Lux speak and learn and form sentences.
She understands child development because she has watched it take place again and again.
And let's face it, she's a Teen Mom star. Of course she's seen other kids develop in real time and noted the differences.
Speech development isn't a race, and Kailyn knows that. Kailyn didn't have to go to bat for Ensley, yet she did anyway.
She's a mother, and she knows kids don't deserve flack for anything, let alone for things that they cannot control.
It's not Ensley's fault that she's Jenelle and David's daughter. No one would choose such a situation if they could.
If you want to throw shade at Jenelle, you will not find a shortage of reasons to engulf her in a storm of shade.
Just don't insult those kids in the process.
