> structurs faults or to environmental causes? In many rural districts in
> this country at least 95 per cent. of women successfully establish their
> lactation. There is no reason to think that with proper management the
> proportion of urban women capable of doing this is less than it is among
> the rural women. An endocrine mechanism which has allowed a woman to
> conceive and give birth does not at that stage fail to provide for
> lactation. There remain a few, less than five per cent., in whom it is
> physically impossible to establish lactation either because of diseased
> or
> malformed nipples, or because the infant cannot suck on account of
> mental
> defect or of cleft palate or other physical fault. All women who are

> brief "practice feeds" twice on the first day and three times on the
> second, while the schedule of five feeds a day was introduced on the
> third
> day. Small infants not requiring the full premature regime received six
> or
> seven feeds a day. If for any reason infants were not put to the
> breast,
> lactation was established by manual expression.
> Estimation of Milk Production -- After each feed the residual
> milk was
> expressed by the mothers. All infants were test-weighed on the fourth,
> seventh, and tenth days, and on intermediate days if necessary, and the
> milk expressed after each of these feed was measured and the day's total
> recorded. The sum of the test-weigh and the expressed milk totals
> provided
> an indication of the "available" milk production for the day.
> Painful Nipples -- Cases of even mild overdistension were
> carefully
> watched and the nipples regularly inspected with a hand lens for damage.

> pain or evidence of nipple damage, lactation being maintained by hand

> the most
> frequent reason for early bottle feeding is primary failure of
> lactation,
> which occurred as the major factor in 36 of these cases (43.9 per cent)
> [NOTE FROM KD: 4% of the total sample]. Of the 36 cases, 28 were
> multiparae, of average age 35.3 years, each with an average of 5-6
> children. Ten of these patients had been able to breast-feed their

> A

> possessed many features in common. The eight primiparae, in particular,
> presented a remarkably uniform picture. Without exception their breasts
> at
> the initial antenatal examination had been described as small and
> inelastic, and of a homogeneous "doughy" consistency lacking much
> palpable
> granular tissue. There had been little or no increase in breast
> development during pregnancy, while little or no colostrum could be
> expressed during the first two days after delivery. As was to be
> expected,

> the
> same general characteristics. Even those who had fully breast-fed their
> earlier infants now showed little or no glandular development during
> pregnancy, and after delivery quite inadequate secretion of colostrum
> and
> of milk. These breasts had evidently failred to respond to the
> stimulation
> of later pregnancies."
>
> He goes on to discuss how many cases of lactation failure were due to
> inverted, "tied" or deformed nipples, severely cracked nipples,
> tuberculosis, other health issues. I love this line: "In addition,
> there
> was one case of puerperal mania and two of nervous exhaustion due to
> domestic worries." Another 11 cases were due to maternal refusal to
> breastfeed.
>
> In the conclusions, he says 4% of their sample was unable to lactate,
