New baby sister is coming

I learned that I am going to be a big brother to a new baby sister. How exciting!! Mommy and Daddy said that she will be here around Halloween time. Mommy said that the baby is growing in her tummy. That is just weird to me. When she told me,at first, I thought that she was kidding. I really laughed hard. Then, she told me that I used to be in her tummy. Now that is even more weird. What is she talking about? Regardless, I am practicing on sharing so that I am ready for her to come. Mommy and Daddy said that I will be a great big brother. I hope they are right!!!
