chromosome deletion 21.1q behavior

My daughter was diagnosed with chromosome deletion 21.1q when she was three.  She has hearing loss in left ear, reflux, sleep apnea but is doing great in school and is in 2nd grade.  The teachers say she is so quiet and a good student.  When she comes home her head turns all the way around and she throws tanturms that babies or toddlers would do.  She will sceam be defient talk back and throw herself on the ground.  iS this normal for her condition?

I would definitely recommend seeing a counselor, preferably one familiar with your daughter's condition. A good counselor can help equip you with the tools you need to address her behaviors. Things will not get better on their own. The sooner you seek help, the better.
