"It appears to me that you still hold to the view that Ariah's death was a terrible accident. It was not," he said.
But Justice Whata did note the immediate steps Archer took to resuscitate her and get help for her.
He also noted that the 31-year-old had a violent upbringing and long-standing behavioural issues.
"I accept that there is an indirect linkage between your very difficult and, at times, violent upbringing, your propensity for domestic violence and your offending. You were not given the tools to manage your anger," said Justice Whata.
He accepted that Archer felt horrible about what happened and it would have a lifelong impact on him.
"I think there is little, if any, real prospect of you repeating offending of this kind," said Justice Whata.
Archer will have to serve a minimum period of 50 percent of his sentence.
