'What's Your Excuse?' Jax Taylor Faces Backlash for Suggesting Vaccines Caused Son's Regression After Brittany Cartwright Split

Jax Taylor is being slammed after implying that vaccinations caused his two-year-old son with Brittany Cartwright's regression, RadarOnline.com has learned. The Valley star, 44, made the claims on social media after he and his estranged wife shared that their toddler Cruz "stopped talking" during a recent episode of their new Bravo show.

While they did not mention vaccinations on The Valley, the now estranged couple allowed cameras to film Cruz with his speech therapist. Fans immediately applauded Taylor and Cartwright for being so open about their child's development struggles — that is, until Jax spewed out his recent theory.

“My son crawled early, walked early, and even spoke early,” Taylor explained. “Then we got him vaccinated and it all stopped.” He didn't specify which jabs he was talking about but at that age, children have usually had a handful of vaccinations to protect them against illnesses like measles, mumps, and more.

He went on to say, "I am not saying vaccines are the cause but what else could it be, how can [Cruz] be talking fully, walking fully then stop two weeks after vaccinations.”

Others weren't so kind and used the opportunity to take jabs at Taylor.

"Having Jax as a father is what caused his son to regress," someone commented. "What’s Jax’s excuse?" shared another. "Jax the idiot said something idiotic shocking," added a third.

Taylor's remarks come less than two months after Cartwright confirmed their separation. While he appears to think their four-year marriage can be salvaged, she doesn't seem too sure.

RadarOnline.com told you — Cartwright has "indefinitely moved out" of their Los Angeles marital home and is living in a rental for the time being.

She recently opened up about the decision behind their split.

"After having Cruz, I realized I wanted more in a relationship," she told Us Magazine. "I need to make sure Cruz isn’t living in a house where his parents are fighting; that could be a horrible way to grow up."

Cartright continued that she'd "forgiven Jax for things that I shouldn’t have over the years," saying, "I stood by him no matter what. But after nine years, that can wear on you."
