I am the mother of 2 adult children, a boy and a girl, now in their 20's. My stepdaugther is 9 and lives with her mother. She is EXTREMEMLY immature for ehr age compared to what my children were at 9. She crawls around on teh floor, speaks in baby voices, calls her fatehr Dadda and rarely sleeps thrugh the night without crying for Dadda (like an infant). She picks at her food like a two year old would and enjoys watching tv shows suitable for a preschooler. She will also throw tantrums in a grocery store (literally stomping and screaming or laying on the floor yelling i hate you) if she does not get her way. Additionally this child has no manners and please and thank you seem to be a foreign language. Is there something wrong with her (ADD some sort of delay, I don't know?)??? It just seems that she is so completely far behind other girls her age. Physically she is beginning to develop, so I am conserned taht her emotional immaturity will soon put her in a vulnerable place when it comes to boys. She doesn't have any friends at school--she seems to compeltely lack in social skills as well. HELP!!!!!
