The man, a 28-year-old from Christchurch, is accused of stabbing the youngster on Tuesday evening at a home on Gilder Close.
A woman in her 50s was also arrested on suspicion of assisting him but has since been released.
The young girl remains in hospital for non-life threatening injuries and is expected to recover, officers said.
She was initially reported as eight years old by local media.
DCI Aimee Schock said the girl and her family are being supported by specialist officers.
