Why must they change

It makes me so sad to see my son get older but it makes me happy. He has change so much since he started grade one. He has developed an additude that i just dont care for and it makes me sad because he was the perfect little boy before school started. Not that he isn't perfect now, dotn get me wrong I would trade him for all the gold in the world. He is my baby boy and he will always be Mama's boy. He just is different. Things like what he wore never mattered to him before now he can only wear certain things which makes my second hand shopping hard. He hasn't developed the knowledge for brand name things yet but I am sure that is to come. My nephew wants Nike Shoes now because they are whats in style and that scares me. he is 7. I never had the need to have brand name clothing. I knew as a child we couldn't afford those things and that was that. You wore what was bought for you and that was it nothing was said. I really hope Austin doesn't develop the taste for brand name things. i just want my baby boy back :(
