Does anyone have links about how bm changes to fit the babies needs?


I am having a hard time understanding how one body, can change the output in order to accomodate a totally seperate body.

I have never heard of bm changing the fat content on a daily basis. I have heard that bm changes according to the child's age.

Toddler bm has more immunities according to Dr. Jack Newman:

I had mentioned to an LLL leader that if we adopted a baby, I would be able to bf'ed as I am still nursing my dd. She said that my "toddler milk" was different than "newborn milk" and I would have to supplement with formula.

As the baby ages, I believe the milk changes. This is due to the fact that the baby is eating more solid food and nursing less.

Also, the milk changes wrt immunities. If the mother is exposed to a virus, her body produces the immunites and those are passed along to the child in her bm. However, if the child is exposed but not the mother, I don't think those specific immunities will be in the bm. The mother has to be exposed.

Well, I can't claim to be an expert on this. This is just what I have picked up.

Fat content can change from hour to hour. http://www.asklenore.info/breastfeeding/additional_reading/mysteries.html

"While the amount and composition of carbohydrate and protein remain relatively constant in mature human milk, the composition of fat is highly variable and is affected within hours and to a large extent by maternal nutrition intake. Gestation,lactation, parity, milk volume, caloric and carbohydrate intake, and weight changes are among the maternal factors that can alter the fat content and composition of breast milk."

Very informative posts, I have only skimmed the links quickly, I will read them better tomorrow and if I have further questions, I'll let you guys now.


Thanks!

The jist I have gotten in the past about variation of components in BM is that the variation is reactory, not anticipatory. If baby doesn't empty the breast well at one feeding, the body ups the protein and vitamin content of the next feeding to compensate. On hot days the body provides more water in the BM. If the baby is premature the content changes even more yet. I also think it is linked to how the composition of milk changes over the lactation period. After 6 months immunities go up because baby is nursing less often, protein and nutrient content goes down because baby is able to take in those things on their own or mom's stores of the nutrients are depleted. Here's some more info of interest:

List of abstracts of studies on fat/protein/lactose content of BM

Of special note:

Possible link between degree of breast emptying and fat content

A great page on the components of breast milk

This isn't a link, but my explanation of what I understand of it.

Above and beyond the antibodies, there is the aspect of heat, for instance: when it's 100F out in the shade, the milk the mom's body makes is more liquid, less fat. Just like you don't like a big heavy creamy meal when it's really hot out, neither does baby. But in winter, there is more fat in milk. Of course, this is in addition to varying from the beginning to the end of a nursing session, with the need for thirst to be taken care of before hunger, so foremilk is "skim" and hindmilk is the high fat "dessert" milk (foremilk is more like soup).

Also, as your child gets closer to weaning, the amount of antibodies go up in milk, as do the amounts of some vitamins and minerals. It has to do with how often you nurse per day and just how concentrated the milk is at each nursing session.

I have read before that the actual *number* of antibodies in any given litre (or other amount) of milk is always approximately the same, from day to day. But as you produce more or less, they get more or less diluted. That is why colostrum has so many antibodies: it is very concentrated, being produced in such small amounts. Weaning milk, say the milk of a child who nurses once a week or something, would also be very concentrated by that rule of thumb.

Your body also basically has a certain "knowledge" of how long after a child's birth you are, and I've also read that if you assign one breast to each child while nursing non-twins, the milk in each breast adapts to each child (I assume based on sucking strength and nursing frequency/length), which is part of the reason why my 2 each have their "own" breast...DD1 always nurses on the right, and DD2 on the left.

I think your LLLL is totally up a tree. I realize that some moms who haven't been bf very often (ie BF a toddler) may not produce enough to begin with, but I think that even milk that is for a "2-yo" will be better adapted to your newborn adopted baby than formula would be!

That's interesting, but I don't know if it makes sense.

Perhaps she was thinking of a toddler that nurses once a day. That is definitely not my dd! at 31 months, she still nurses pretty often while we are at home, very rarely when we go somewhere. I wonder if it has to do with her being an only child. Not much to distract her and she gets bored.
