A toddler died after his father force-fed him a mixture of cereal and bread - causing his lungs to fill with the substance and drowning him in his food, a court heard.
The three-year-old was allegedly regularly made to lie across his father's lap as his cheeks were pinched together and the porridge-like mixture poured into his mouth from a cup.
But in November last year, the youngster returned home from nursery to be fed for the last time, the Old Bailey in London heard.
His 32-year-old father, from north-west London, who cannot be named for legal reasons, is charged with manslaughter and cruelty to a child.
Jurors heard that, after being forced to eat, the toddler sometimes vomited and "the defendant would become angry, and slap him or send him to bed." But on one occasion it went "terribly wrong", said prosecutor Simon Denison QC.
