Hi,

I have a 9-year old boy and he is on his way to 4th grade. I am worried with the sudden change in his behavior and preferences. Aside from having a new member in our family, his baby sister, are there any possible cause for this? He now prefers to stay in the house and play with his bike and his video games. At times, he also gets shy around people which was very opposite way back then. Is this change normal?
