He will have to serve a long term of imprisonment for such grave offences
Nicholas Hilliard QC
Dobby, 23, who has a long criminal record, admitted manslaughter of Makayah and his aunt in Penge, south London.
He also admitted causing serious injury to Yahla by dangerous driving.
Dobby drove through red lights and down oneway streets at speeds reaching 100mph as he tried to escape police.
Traces of three different drugs were found in Dobby's system after he was arrested
After ploughing into Makayah and his family he fled from the overturned car, leaving the boy and his aunt to die.
The twins were pinned under the car and rescued when up to 20 passers-by lifted it off them. Dobby, of no fixed address, was tackled by people nearby.
Tests later showed there were traces of heroin, cocaine and morphine in his system. Makayah had appeared in an Asda advert and just landed a lead role in a major new TV series.

Ronnie and Reggie Kray's mugshot after their arrest in the 1940s
Yesterday Dobby, the estranged son of millionaire businessman Mark Dobby, appeared at the Old Bailey via video link from High Down jail, south London.
Recorder of London Nicholas Hilliard, QC, adjourned the hearing so the danger Dobby poses to the public can be assessed.
He had been freed from jail just weeks before the killings. Dobby had served half of an 18-week sentence for receiving stolen goods and was on licence when he killed Miss Cooper, 34, and her nephew Makayah.
Days before the hit-and-run, Dobby was chased by Kent police in the same stolen car
Five days before the crash, he was chased by police in the same stolen car in Snodland, Kent. Officers called off the pursuit as Dobby drove so recklessly.
His criminal record includes a 2010 conviction for aggravated vehicle-taking. Dobby, whose mother is understood to have died of a drug overdose, could face life when sentenced on March 10.
The judge said: “The defendant can be under no illusions, he will have to serve a long term of imprisonment for such grave offences as these.”
