About my sister

So my sister is having her 3rd baby today. Ahe has 2 boys and is now having a girl. I had my first baby last yr. I thought she would throw a baby shower for me but she didnt. She didnt even get me anything for Jenibelle. She was there for my delivery. But thats all. She even asked me to watch her kids after a week i had given birth. Since im soo damn nice. I did. Id take my newborn out in the coldwalk down 3 flights of stairs and drive to her house. Anyways. Should I get her anything?
