It was the perfect first time to babysit because my parents were right next door. So if anything went wrong, I could call them for help. And also since it was during the day, I could just play games with the kid the whole time and I didn’t have to worry about the kid falling asleep.If you are babysitting for the first time, I think you should do it during the day.
