My kid is home sick instead of at the babysitter's (who is, herself, sick), and it's super heartbreaking. She's not devastatingly ill or anything. It's a sore throat and coughing. But she's too young to understand that whining and crying actually make it worse. So she screams, then moans, then cries, and generally stays unhappy between fitful, short naps. And there's nothing I can really do about it other than frequently give her water, cold and soothing food, and lots of hugs (when she's not being too grumpy for me to hold her).
