Is it normal to have to use characters to communicate with parents

Is it normal that I have to use my many characters to communicate with my family? When talking to a member of my family I often have to be holding a stuffed animal while doing the animals voice and making it do things. When I am not in character as one of my critters my family finds me very hard to talk to and my mother accuses me of giving everyone attitude (as far as im aware its my natural personality. Also if someone is upset at me I find i have to take out my animals and make them talk to said person to get them to stop being mad at me. This would be okay if I was a child but im almost an adult and I find it quite ridiculous that i have these issues. So is this normal or do other people have to do things like this?
