It seems that the professionals of health and the population in general have increasingly clear that breast-feed while you are pregnant is not dangerous for the new baby and that is something that many women do without having to recommend weaning due to pregnancy.
Now, if the child, if the largest, is feeding breast milk during pregnancy, something that does not happen in a first pregnancy because neither child nor the mother produces milk, What produces the mother when the second baby is born? Colostrum? And if you produce colostrum, is this just as a mother who does not give the chest? Is it perhaps a mixture of colostrum and milk? We will try to answer these questions for maternity pillows through anylistintheus.com.
Studying nursing mothers in tandem and mothers who do not
To do this, we will focus on a study by Alba maternal lactation (breastfeeding support groups Association) and by the Nutrition Department of the Complutense University of Madrid, who analyzed and compared samples of colostrum of women who are breastfeeding to a baby only and women giving the breast the baby and another brother.
In total, samples of 25 women are caught. Fifteen making tandem and ten who did not. Milk samples were obtained during pregnancy from the first in the fifth, sixth, seventh, eighth and ninth month. In addition, Colostrum samples were collected at two to four days, a week, two weeks and a month after giving birth.
Of the latter, which only gave the chest to a baby, samples were collected after the equal birth than in the first, two to four days, a week, two weeks and a month after giving birth.
To try to achieve conclusive results were compared samples based on various immunological and biochemical parameters that are present both in colostrum and mature breast milk, but in very different concentrations. Namely: two cytokines (TGF– 6), immunoglobulins, IGA and total IgGs, lactose, proteins, fats and vitamin B12.
Lack of budget made that in the end only is could analyze samples from week 30 to 35 of pregnancy of mothers who were tandem, Colostrum two days after giving birth and the milk matures into the month of having the baby (yeah, I think just like you, a pity because it would have as much information about it…).
A surprise: mothers who breastfeed their children during pregnancy just produce milk
The study served, bounce, to have additional information about something that is known from a while ago: mothers who breastfeed their children during pregnancy produce very little milk. In fact, there are hardly producing nothing. This explains why many children are weaned when his mother becomes pregnant. This explains why my sons Jon and Aran weaned into the three months following pregnancy, knowing that “there” already not leaving anything.
As they explain, no mother was able to extract the sample alone, or manually or with a breast pump. Apparently, with patience, with time, with insistence, were able to remove (miserable) 5 ml of each breast. Obviously, these mothers realized then that their children not suckled by a question of food, but by the emotional bond, for a short time with MOM.
Comparing samples of colostrum
Samples of colostrum of the 25 women were the same orange yellow typical of colostrum. The milk collected during pregnancy, on the other hand, was white. This means that It could be from the delivery when the woman’s body begins to think about the baby, adding the typical colostrum substances which give density and that specific color.
When analyzing all samples to look for differences observed that, despite having individual differences in all samples, the averages of all parameters were very similar in the 25 samples of colostrum, without that there were statistically significant differences between them: TGF – 300 ng/ml; IgA: ~ 40 mg/ml; IgG: ~ 0.6 mg/ml; lactose: ~ 4.7 g / 100 ml; protein: ~ 2.3 g / 100 ml; FAT: ~ 2.7 g / 100 ml; vitamin B12: ~ 250 mg/100 ml. Then you can see these values compared in a chart:
Analyzing samples of mature milk after childbirth (and also those obtained) during pregnancy noted that There were no statistically significant differences in the composition: (TGF-proteins: ~ 0.9 g / 100 ml; FAT: ~ 4.5 g / 100 ml; vitamin B12: ~ 45 mg/100 ml).
Yes they found differences, obviously, when they compared samples of colostrum breast milk samples, demonstrating that a pregnant woman’s milk changes to birth the baby to produce colostrum and then returns to change, when necessary, to again be milk, according to the needs of little brother, and not the older brother.
In the following chart you can see the milk of pregnant women was almost equal to mature milk appearing after birth, after the colostrum and milk of transition.
The mature milk is not clear at what point changes to become again in colostrum, since all samples of women were not analysed in the ninth month, before giving birth. Apparently If the samples of three women were studied and, there is no data, the researchers explained that, without even the baby being born, samples were more similar to colostrum believed to mature milk, so that the change happens a few days before the birth.
Think all commented that the questions are answered. Children maman milk mature during the pregnancy, although hardly anything maman (some perhaps take something, others may not be able to remove anything) and when the baby is about to be born the milk changes to colostrum, giving you what you need in every moment. A colostrum with the same properties as the other women, that will be transitional milk and then milk mature, also with the same properties that any mother’s milk, nursing one older child or not.
