The Shameless star had been keeping her family life very private before she shared the first photo of her baby girl on Instagram earlier today.
In the caption, Rossum explained why she posted the photo of her daughter, and I think it’s something we all need to hear.
“When I was pregnant I got vaccinated,” Rossum explained. “Not only did we have a healthy, beautiful baby girl but we also just learned our daughter now has antibodies.”
She added, “In short, stop being an irresponsible idiot and get the vaccine.”
