An imaginary friend is a sign of INTELLIGENCE. hehe. So, it's actually a GOOD thing. I wouldn't worry about it at all. So far all my kids have had imaginary friends. It doesn't mean they are being neglected somehow or that you are doing anything wrong. It's just something kids do, and if you look it up, it's a sign of intelligence...it's really nothing to be worried or upset about or to even view in any negative sort of way. When my kids have talked about their imaginary friends, I don't make a big deal out of it. I don't tell them the friend isn't real. I just react low key. Sometimes they tell me funny things that their friend did, and I laugh with them. It's totally a good thing, if anything.
