I've noticed just how big he's gotten this week because:
1) He now spends most of his time bbm'ing his friends
2) I stroked his cheek this morning in the car outside school (he has the softest most beautiful cheeks and I would rub them all day long if I could) and he went "MOM!! My FRIENDS!!"
3) He has asked to go to the movies this Friday with his friends - WITHOUT ME!!
