Don’t mess with JWoww! Jenni “JWoww” Farley was accused by several social media users of not putting sunscreen on her 2-month-old son, Greyson, after she shared a photo of him in the pool with her husband, Roger Mathews — and she was not happy about the backlash.

The Jersey Shore alum, 30, posted an Instagram shot of her hunky hubby holding the infant, who looked adorable in a blue T-shirt and a straw fedora, in the pool on Sunday, July 10. Shortly afterward, dozens of critics slammed Farley for the photo.

“Way to small for a pool,” one Instagram user wrote, while another added, “Put sunscreen on that child.”

Moments later, the mom-of-two hit back with a second post, in which she showed her 4.5 million Instagram followers her homemade sunscreen concoction.

“Not even sure why I am even doing this but I feel like schooling people on my previous post,” she wrote. “First off, my son is two months and in a salt water pool up to his belly... Probably for a total of 3 minutes. But second is where I need to really educate trolls... Let me explain to the haters that decided to comment about no sunscreen and the dangers bla bla bla.”

JWoww continued, “My son actually does have sunscreen on. It’s the same concept as diaper cream. Probably even better than the crap s--t you lather your children in. Remember ass holes im in the tanning industry and pride myself on knowing this. So, here is what I mixed for my son so I know for the 2 minutes he would be safe: Coconut Oil- SPF 4-6. Zinc Oxide SPF 2-20 depending on how much used. Carrot Seed Oil - SPF 35-40…”

The reality star snarkily concluded her post, “Go enjoy your Sunday now,” with a nail polish emoji, an unamused face emoji and a middle finger emoji.

Farley isn’t the only star who recently came under fire for an Instagram post about her kids. The Hills alum Kristin Cavallari shared a sweet photo of her family at the beach on July 4, but many social media trolls were seemingly appalled by Cavallari’s sons’ thin physiques.

The 29-year-old fashion designer, who is married to Chicago Bears quarterback Jay Cutler, swiftly responded, quipping, “Yep, I starve my children. Just blocked the most people I’ve ever blocked in my entire life. Happy 4th hahaha.”
