Sharing a selfie while holding sonOzzie, 9 weeks, on her Instagram Story Thursday, theThis Is Usstar, 38, revealed that she’s juggling keeping her newborn healthy while sonGus, 22 months, is sick.

She captioned the shot in checklist form, listing that she has a “toddler with the flu and croup,” an “exhausted household,” and is “trying to keep myself and the newborn healthy and nursing around the clock.”

TheMayo Clinicdescribes croup as “an infection of the upper airway, which obstructs breathing and causes a characteristic barking cough,” and notes that the infection generally occurs in children.

Despite the tired mom’s tough time, she managed to exercise while her kids slept, as she shared in a later post.
