Fans are giving Jessica Simpson a piece of their mind.

The actress, 42, took to Instagram over the weekend and shared a series of images of her family on a lake vacation. In some pictures, Simpson’s daughter, Birdie, 3, was seen with a pacifier in her mouth.

Her comment section quickly filled with fans disapproving of Birdie still using a pacifier at her age.

"And before anyone starts with the oh she’s a public figure, NO that does not give you a free pass to say horrible things, she is human, this is her space & we know nothing about her personal life aside from what she decides to share."

Simpson has not commented on the negativity and instead shared a birthday Instagram post where she said she’s proud of her "faith, resilience and strength."
