My l1 year old has several stuffed animals that she has held onto through the years. Through the years she got rid of toys, but held on to several of them and just always said she was going to keep those. She didn't really play with them very much in the past although she has had names for each of them since she was about 6 years old. Recently she started taking turns sleeping with each of them. She says they are "real". I've asked her to do really mean they are real? But she doesn't quite give me a real response. She does well in school. She has several friends at school, but this still concerns me.
