A woman says she doesn’t want her in-laws kissing her child after he developed an eye infection — but they aren’t listening.

In a post shared to Reddit, the woman writes that her 5-month-old son “has had an eye infection for the last 2-ish weeks.”

“We thought it was pink eye at first but once the antibiotics were done, the eye got worse than it was originally less than 12 hours later,” she writes.

So, the couple took the little one to an eye specialist, as they believed it could be Herpes Simplex Virus (HSV), a viral infection that can cause sores and blisters.

“My husband and I are not carriers of the virus and that’s a known fact based off of bloodwork,” she writes. “The only other person that kisses my son (even though we frequently basically beg them not to…) is my MIL and FIL.”

“The doctor told me that absolutely nobody other than my husband and I should be kissing babies hands, feet, head or face,” she continues. “Perfect, now there’s a medical professional saying that and it should be respected, right?”

However, when she and her husband advised his parents of the situation, they began sending passive-aggressive messages.

That morning, her in-laws texted her: “It’s better not to bring him to my house again in case something happens to him, it was definitely us. Don’t worry, I won’t kiss him anymore. I’m sure that all the places they took the child and all the people who carried him are clean and healthy. The Publix carts are cleaner than us.’ ”

Hours later, they sent another message, calling the couple “disrespectful” and slamming them for bringing the infant out in public, all while “grandma can’t give him a kiss because it will make him sick.”

The woman writes that she doesn’t know how to respond, and feels “like a horrible person for protecting my baby.”

Others on Reddit are urging the woman not to feel bad, with one writing, “If they can’t respect that decision, they don’t get to see him/hold him or ever have him alone.”

“They’re out of line and they don’t deserve a response,” another adds. “You have enough to worry about without adding their feelings to the list. Deal with them later, if at all. They can see the baby when they can be adults who can be trusted with a baby.”
