Im very concerned. my step daughter is 4 1/2. she is an only child. I have been in her life for two years. She lives with her mother but visits on every other weekend. She goes to catholic preschool. she goes to dance class. on paper she seems to have a very ordinary life but her behaviors are a little "weird" to say the least. At parties she will not play with children. She is socially awkward, not shy, but disturbing. she will only play with children one on one. even at school. on halloween she refused to go into the room where the 16 other kids were playing at a party. she stayed in the kitchen in the dark coloring in a book and eating candy. she has several imaginary friends. i understand that having AN imaginary friend is not weird for an only child who feels lonely but she has at least 6. she has been caught dancing nude, at points gyrating like a stripper and when questioned she says im practicing for my naked dance parties with all my friends when i grow up. she claims her imaginary friends are watching her. she walks around naked all the time. she tells people about her "naked dance parties" with her imaginary friends. Im embarrassed when she does, im confused and im worried. any input guys??? i dont know what to think and all y thoughts on this are not good ones. HELP!!! thank you so much for your time.
