Sleepy but Kids Come First

I work from 8 am to 4 pm today. I was really tired because I worked from 2pm to 10pm last night. actually it's supposed to be my day-off but someone call in so I have to work because my boss told me so. It's  my second time doing a morning shift. I thought it be stressful but it's not all. I like working in the morning now compare to the night shift. What It's not so tiring and it's more fun. So right now, I'm so sleepy already but the kids are still watching a movie so I have to wait. I wasn't able to really hangout with them as often as before. So I'm taking advantage of any free time I have and make sure I spend it with kids.
