Nappy Change
(IN PHOTO) Argentine teenager Pamela Villarruel, a mother of seven, looks at her mother Magdalena (R) changing a diaper while accompanied by her brother Jose (L) at her parents' home in the town of Leones in Cordoba Province, northern Argentina, May 10, 2008. Pamela, 17, bore all seven children in just three pregnancies, having her first boy in 2005 when she was 14 and the other six girls in two deliveries of triplets in the following two years. Pamela and her children currently sleep in the living room of her mother Magdalena who supports them all by house cleaning. The father of Pamela's first son abandoned them, the father of the first set of triplets was forced out of the house by the family for beating her, and Pamela refuses to identify the father of the more recent triplets. Magdalena requested to have her daughter's fallopian tubes tied to avoid any further pregnancies, but was denied as Argentine law prohibits the procedure to be done on minors.

A 23-year-old Chicago man was so pissed off that the 18-month-old son of his girlfriend peed on him while he was changing the toddler’s diaper on Thursday. In his nappy rage, he pummeled to death the child.

Martin Alvarado Jr admitted to authorities in Cicero that he lost his cool, and in the process, he killed Edwin O’Reilly, reports the New York Daily News. He was charged with first-degree murder after he admitted on Sunday to the crime through a videotaped confession.

His rage continued in jail when he trashed his cell overnight that his appearance in a bond court on Monday morning was cancelled, said Cicero town spokesman Ray Hanania. Besides the murder charge, Alvarado is facing neglect and abuse charges together with the mother of Edwin.

The Illinois Department of Children and Family Services took custody of an older sibling of Edwin while an investigation is going on.

The bladder of infants fill and empty without control. Most children in the US gain control of their sphincter muscle by four years old, according to Until they have that control, younger children urinate by a reflex in their spinal cord.

As they become older, children learn to block that reflex through signals from their brain. Eventually, the brain learns it could control when the bladder contracts and also when to stop contracting.

Adults, though, are expected to know how to control their rage. Alvarado will learn the price of failing to control his anger when he receives his sentence from the judge handling the case.
