A study based on the work by Millicent Lucy Coleman on Enuresis (bedwetting) on children in the National Children's Home during March from NCH records over five years.
--
The children that are bedwetting number roughly 14 of every 100 boys, and 7 of every 100 girls in the Children’s Home Branches (age 4-14).
In the NCH  Approved Schools, the proportion is 17 boys of every 100, and 3 of every 100 girls (age 9-14).

Bedwetting during March over five consecutive years.

Boys NCH Children's Home Branches
Year 1. 1355 Boys. Number affected 152 = 13.7% Wet beds in month 1170.
Year 2. 1095 Boys. Number affected 153 = 13.8% Wet beds in month  992.
Year 3. 1222 Boys. Number affected 162 = 13.3% Wet beds in month 1024.
Year 4. 1235 Boys. Number affected 184 = 14.9% Wet beds in month  942.
Year 5. 1168 Boys. Number affected 157 = 13.4% Wet beds in month  921.

Boys NCH Approved Schools
Year 1. 507 Boys = Number affected 107 = 21.1% Wet beds in month 842. 
Year 2. 432 Boys = Number affected   66 = 15.1% Wet beds in month 488.
Year 3. 392 Boys = Number affected   59 = 15.1% Wet beds in month 408.
Year 4. 357 Boys = Number affected   64 = 17.9% Wet beds in month 439.
Year 5. 336 Boys = Number affected   50 = 14.9% Wet beds in month 402.

In the Branches and Approved Schools it was taken
"Regular" as more than two or three times a week (Average 4).
"Frequent" as more than three times a month (Average 6), 
"Occasionally" as less than this (Average 2).
Scrutiny of these figures shows that almost half of all bedwetting can be regarded as occasional, leaving the other half as the more serious problems.

Regularity of events NCH Children's Home Branches
Year 1. Regular 36.1 %, Frequent 19.5%, Occasional 44.4%
Year 2. Regular 24.6 %, Frequent 27.5%, Occasional 47.8%
Year 3. Regular 24.3 %, Frequent 29.1%, Occasional 46.6%
Year 4. Regular 23.7 %, Frequent 30.0%, Occasional 46.8%
Year 5. Regular 21.7 %, Frequent 35.0%, Occasional 43.3%

NCH Approved Schools
Year 1. Regular 35.5 %, Frequent 29.0%, Occasional 35.5%
Year 2. Regular 26.9 %, Frequent 26.9%, Occasional 46.2%
Year 3. Regular 26.0 %, Frequent 20.0%, Occasional 54.0%
Year 4. Regular 28.4 %, Frequent 28.4%, Occasional 43.2%
Year 5. Regular 27.1 %, Frequent 28.8%, Occasional 45.1%

In both the Branches and the Approved Schools. The most serious cases therefore appear to be diminishing in number, although the frequent cases are increasing. The magnitude of the problem is not so great as it sometimes appear. Socially it is a matter of importance, particularly as a child gets older.
It is therefore imperative that assistance both medical and psychological be given where bedwetting is either regular or frequent.
In the Children's Homes, the age group supplying the highest percentage compared with the numbers in the Homes are the age of four at 20%, at five there is a decrease to 18% at six 15%, at seven 14%. In the junior group at eight 18%, at nine 12.5%, and a rise at ten to 13.5%.
The age make up in the Children's Homes is 30% in the age group of 8 - 10 years, thus a Sister may have more junior boys wetting the bed than that of a younger age group. It appears that there are more children of junior school age affected than any other age group. We do not know why so many boys of eight to ten years are now bedwetting, as many of them did not so when younger.
One theory is that for the younger boy under the age of eight it was a more tolerated event, and on reaching eight and above more sanctions are now apparently given out over the matter. There is a drop after the age of ten years, and then a gradual descent until fourteen years and above.
Unfortunately more than a quarter of our bedwetting boys are of secondary school ages. The social implication of this is very serious, since bedwetting limits opportunities for holidays and visits; and so indirectly hinders the individual development of the child.
In the NCH Approved Schools, the age range is 10-14 years, except for year 1 when the ages were 9-14 years the peak for bedwetting in these schools is up to 13 years of age.

The study was based on one full month over five years. It should be noted that from full years records the percentages could be increased as to the numbers of individuals who experienced bedwetting during one full year, but many of these were isolated incidents or occurred very infrequently.
In the case of boys, including those under junior school age that wet the bed once or twice in a single year was 92%, whilst in the case of boys of junior school age including those that would experience very occasional bedwetting was around 74%.
In the NCH Approved Schools with an age range of 9–14 years the percentage was 76%. With girls of all ages affected at lower rates. Thus it would give rather incorrect representation to show that 74% of Junior School boys in the NCH Homes and 76% of  NCH Approved School boys were bedwetting, as these very occasional events should be discounted.

Every effort should be made to prevent the formation of a habit, since the greatest promise of a cure seems to lie in the first year. Some branches are more successful than others in creating a tradition that helps children to avoid bedwetting. Some of the largest and some of the smallest seem most equally successful.
A great Influx of new children at one time into the same branch may temporarily raise the ratio. Its fall seems to depend on the speed with which the children settle to their new life. There is a consensus of opinion both in the Home and outside that it is a symptom of general nervous disturbance.

It was also noted that on average in the Children's Homes during the five years 2.6% of boys of school age who were wet during the day (30 per month). There was little difference between the 6 year old and eight year old age groups in this matter, and that 1%  (12 per month) suffered from soiling during the day.
In the NCH Approved Schools there were 2% who wet during the day (8 per month) and up to 2.8% soiled (10 per month).
