A four-year-old girl from the Gold Coast remains seriously ill at the Royal Children’s Hospital after allegedly being poisoned by her mother.

Police allege her 22-year-old mother began feeding her daughter in June last year with chemotherapy drugs reportedly bought over the internet.

The woman was charged with grievous bodily harm on Wednesday and appeared in a Brisbane court on Thursday.

She did not apply for bail, and will remain behind bars in police custody until her next court appearance next month.
