Что касается
ночей, есть вот такая довольно подробная статья:
http://en.wikipedia.org/wiki/Nocturnal_enuresisЦитата:
Medical guidelines vary on when a child is old enough to stay dry. Common medical definitions allow doctors to diagnose PNE beginning at between 4 to 5 years old.
Считать мокрую кровать хоть какой-то проблемой большинство медиков начинает между 4 и 5 годами (а мы в разделе "Малышок - от года до трех"
).
Цитата:
Neurological-developmental delay
This is the most common cause of bedwetting. Most bedwetting children are simply delayed in developing the ability to stay dry and have no other developmental issues. Studies suggest that bedwetting may be due to a nervous system that is slow to process the feeling of a full bladder.
Наиболее частой причиной является задержка неврологического развития (не знаю, как правильно этот термин переводится
). У большинства детей с такой проблемой других проблем в развитии не наблюдается. Исследования показывают, что причиной является замедленный процесс обработки нервной системой наполненности мочевого пузыря.
Цитата:
Most girls can stay dry at night by age six and most boys stay dry by age seven. Boys are three times more likely to wet the bed than girls.
Doctors frequently consider bedwetting as a self-limiting problem, since most children will outgrow it. Children 5 to 9 years old have a spontaneous cure rate of 14% per year. Adolescents 10 to 18 years old have a spontaneous cure rate of 16% per year.
Approximate bedwetting rates are:
Age 5: 20%
Age 6: 10–15%
Age 7: 7%
Age 10: 5%
Age 15: 1–2%
Age 18–64: 0.5–1%
As can be seen from the numbers above, a portion of bedwetting children will not outgrow the problem. Adult rates of bedwetting show little change due to spontaneous cure. Persons who are still enuretic at age 18 are likely to deal with bedwetting throughout their lives.
В 5 лет 20% детей (каждый 5-й!!!) писают в постель время от времени. Мальчиков таких больше, чем девочек.
Вот ещё про механизм работы всей этой системы интересно (ещё, получается, гармон какой-то должен начать вырабатываться):
Цитата:
Two physical functions prevent bedwetting. The first is a hormone that reduces urine production at night. The second is the ability to wake up when the bladder is full. Children usually achieve nighttime dryness by developing one or both of these abilities. There appear to be some hereditary factors in how and when these develop.
The first ability is a hormone cycle that reduces the body's urine production. At about sunset each day, the body releases a minute burst of antidiuretic hormone(also known as arginine vasopressin or AVP). This hormone burst reduces the kidney's urine output well into the night so that the bladder does not get full until morning. This hormone cycle is not present at birth. Many children develop it between the ages of two and six years old, others between six and the end of puberty, and some not at all.
The second ability that helps people stay dry is waking when the bladder is full. This ability develops in the same age range as the vasopressin hormone, but is separate from that hormone cycle.
The typical development process begins with one- and two-year-old children developing larger bladders and beginning to sense bladder fullness. Two- and three-year-old children begin to stay dry during the day. Four- and five-year-olds develop an adult pattern of urinary control and begin to stay dry at night.

Ребенок это труд. И приучить не писать ночью дело одной недели. А то и меньше. А потом будет крепкий сон и Ваш и ребенка. 
сорри
а потом сушку во владивостокском климате...
А с пистолетом и у нас ходят уже.
