Co-parenting is hard, and it can be harder when you don’t have a good relationship with the person you're trying to do the co-parenting with. Kailyn Lowry and her ex Chris Lopez have a very strained relationship these days, and they haven't tried to keep it a secret. After their romantic relationship went south, they've seemingly struggled to work together to parent their sons, Lux and Creed. Chris has gotten in the habit of airing out his grievances on social media, and this time is no different. And this time, in the process of voicing his frustration, he dealt Kail some low blows, even going so far as to mock the number of children she has.

Chris shared a lengthy rant against Kailyn on Instagram.

In a since-expired post on his Instagram Stories, Chris really let Kail have it.
"Bro, ain’t nobody more miserable than my baby mama, bro. My first baby mama, Kail Lowry," he said in the video, according to Us Weekly. "Ain’t nobody more miserable than that chick."
He certainly didn't hold back any of his feelings.
Next in the rant, he accuses Kail of "holding" their boys from him while "passing them on to motherf—ing nannies" instead.
"Kids on Thanksgiving break and you ain’t gonna let the kids be with their dad, but it’s technically dad’s week?" he asked. "You need to grow the f— up, seriously, and stay the f— off your back."
He also accused Kailyn of being a liar.
Chris wasn't done there. He went on to post a follow-up video, accusing Kail of "lying and manipulating" people, making it difficult for him to spend time with his sons. "Y’all thinking I’m f—ing lying and s—? What do I got to lie for?" he asked.

Apparently, there was also some drama around parent-teacher conferences.
According to Chris, the reason for all of his current frustration stems from what happened at a parent-teacher conference for one of their sons.
"I just left my son’s parent-teacher conference. When I signed up for my son’s parent-teacher conference, his mother was not signed up at all," he explained.
"Now, it’s ironic that I mention that I’m gonna be at my son’s parent-teacher conference today, and then, all of a sudden, the teacher just mentioned, 'Oh, yeah, she just signed up for a parent-teacher conference, so I can’t give you the papers now.' Cool, alright."
He alluded to some sort of fight in December, but it's not clear what he means.
At the end of his rant, Chris actually thanked Kailyn for giving him the motivation to "beat the dogs—- out of my opponent on December 8" — whatever that means.
It’s hard to know what exactly he is referring to, but hopefully, he and Kail are able to iron things out for the good of their sons.
