The placards come in a variety of colors and different messages depending on how forward the parent wants the message to be. Other sites, like Amazon, are also selling the signs. The signs cost around $7.00 to $11.55 on Etsy and AmazonKARE 11 reported the signs are getting attention on parenting websites and forums.

While a person can get the flu all year around in the U.S., the virus is most common in the fall and winter, the Centers for Disease Control and Prevention [CDC] stated. The American Academy of Pediatrics [AAP] recommends a child should be given the flu shot when they're six months of age or older. During the 2017-2018 flu season, 172 children died, the CDC said.

The AAP also recommends that a parent use canopies or covers on their child's stroller which can help keep "germ-covered hands from reaching in and touching your baby."
