Hilary Duff reveals baby daughter has hand, foot and mouth disease

The Lizzie McGuire actress explained in a video on her Instagram Stories that she was struggling to be at work on How I Met Your Father this week knowing that Mae is at home with the infection, which causes mouth ulcers plus spots and blisters on the hands and feet. "None of my other kids have ever had hand, foot, mouth, so I've never seen it before and that looks awful.” Hilary then explained that she hasn't been able to look after Mae because she has to work.
