Hilary Duff's youngest child Mae is suffering from hand, foot and mouth disease, the star revealed on Instagram.

"That looks awful," she said, about the rash her 16-month-old Mae had as a result of the sickness. "None of my other kids have ever had hand, foot [and] mouth, so I've never it seen before," Duff said on her Instagram Story.

"I haven't been able to be with her all day because I'm at work," she revealed.

"I love my job so much but this is just a little shoutout to working parents who have to leave their kids in times that don't feel natural," Duff said. "And it kinda like goes against everything in their body to not be with them in times like that."
