My son is 9 and on Monday, he received his first phone number from a little girl. I'm so not ready for any of this and definitely not ready for my little boy to grow up. He is so excited about calling this little girl, and I'm not sure what to do. The first time I talked to a little boy on the phone I was in 6 grade, but my son is in 3 grade and not sure how to handle this situation.
