Today , I discovered that I have the capability to heat up a bottle ( the old fashioned way ) with one hand , while bouncing a screaming baby with the other . Wow . Not so much fun . Good to know I can do it though . Today was my first official Babysitting the Niece event ( for more than 30 minutes ) .
According to the above context, answer the following question.
Why is the speaker with a baby ?


Because they are babysitting their niece .
