Kurt Delves said he was frustrated because he couldn't make 10-week-old baby Harli Reid stop from crying. So he shook her vigorously. He admitted it was a "momentary loss of control." Baby Harli's cries, however, will no longer be heard.

Mr Delves, who was only 20 at the time he fatally injured baby Harli Reid, has been sentenced to three years and nine months.

The incident which happened on December 17, 2010 started when the now 23-year old Mr Delves went shopping with baby Harli and her mum, Donnika Reid. Presumably exhausted, the father and daughter went home ahead of Ms Reid.

Mr Delves told the court he got frustrated with baby Harli because she won't stop crying when he bathed her before bed. Prosecutors said that this frustration pushed Mr Delves to loose his control, eventually shaking baby Harli.

The violent shake which occurred several times gave off 'catastrophic' injuries to her brain. She was rushed to the Birmingham Children's Hospital and placed on a life support machine. She died the following day.

"Babies are vulnerable and defenceless, we all know that," the court heard just before Mr Delves received his penalty.

"They can often be noisy, they can often be demanding, but they are always vulnerable and defenceless."

"As you know, it is the duty of every parent to protect their tiny little baby. Harli was a very loved and very well looked after child."

Prosecutors further told the court that Mr Delves initially planned to fabricate a story to cover his killing of the newborn. He was found to have supposed to say that baby Harli fell ill while in the bath, that the child flinched and became floppy when he splashed water in her face and that would be the only time he shook the baby in an attempt to rouse her.

Police authorities however were able to lay down sufficient proof to show the baby had been shaken with more than enough force to render those fatal brain injuries.

Mr Delves, on the second day of his trial, changed his plea to guilty to manslaughter.

The young father, according to Detective Constable Lyndsey Yates, was presented as a very hands-on father, often taking the lead when bathing, feeding and changing nappies.

"But, in what appears to have been a momentary loss of control, he snapped and shook his daughter in frustration at being unable to stop her crying."

"He caused fatal injuries - injuries he then tried to cover up by inventing a story about how she'd fallen ill whilst in the bath."

"We were able to expose those lies and Delves was eventually left with little option but to admit his actions."
