This has been such a huge week for you. You went from little sister to middle sister, and no longer the baby of the house. It wasn’t as easy for you accepting this role as it was for your sister when she became the big sister. You’re warming up to little brother and I’m sure you soon will be proud of your role as middle/big sister. He’s not very interesting to you right now, I totally get it, but he will find his way into your heart soon. I’m sure of it.
