My son (6) is terrified of growing up

Has anyone had experience dealing with your child's anxiety over growing up?This has been going on for about a year. It all started when one day I was just shocked at how big my baby has become and exclaimed to him " wow you've gotten so big. Your growing into a handsome boy. You used to be a small baby that fit inside my tummy and now you are growing and growing.... Etc" then he had this weird look on his face and asked " what happened to baby Charlie?" I said " you are baby Charlie, you've just grown up and you aren't a baby anymore." He started crying and said he doesn't want to be big and he doesn't want to grow up.If an adult asks " what do you want to be when you grow up?" He immediately and adamantly says he doesn't want to grow up.On his birthday this year, we were so excited the night before. We were all talking about his birthday. I explained that from now on when someone asks how only you are, he will now say 6 instead of 5. This sent him into panic mode. He was crying and saying he didn't want to have a birthday and grow older.We have strategies and tools to work through anxiety with him. But with this topic, it doesn't seem to go away or help.Any advise? via /r/Parenting http://ift.tt/2lZDkV0
