Let Down Reflex

I'm having a problem in getting let down reflex nowadays. While browsing, I found this article. Thought of sharing and hoping it will benefit us all.

The Let-Down Reflex (Milk Ejection Reflex)

What is the let-down reflex?

When you breast-feed, your baby's sucking stimulates nerves in your nipple. These nerves carry a message to your brain, and a hormone, called oxytocin, is released. Oxytocin flows through your bloodstream to your breasts, where it causes tiny muscle cells around your milk glands to squeeze milk out of the glands and into the milk ducts. This is known as the let-down reflex or the milk ejection reflex.

Once your let-down is working well (usually by 2 weeks after delivery), you may feel a pins-and-needles or tingling sensation in your breasts when you nurse or pump. Milk will usually drip from one breast while you are feeding on the other side. Sometimes your let-down will occur when you hear your baby cry or think about nursing your baby. A well-functioning let-down reflex helps ensure your breasts get emptied and your baby is easily getting milk.

Sometimes a woman's let-down reflex doesn't work as well as it should. This can cause breast-feeding problems. For example, you may have problems emptying milk from your breasts or your baby may not get enough milk.

What causes a poor let-down reflex?

Several situations may prevent the let-down reflex from working well.

  • You may have severely sore nipples that cause you to tense up before each nursing.
  • You may be stressed, anxious, or tense. For example, you may be trying to pump breast milk during a short break at work.
  • You may be separated from your baby. For example, if you have to pump at home while your premature baby is still in the hospital.
  • You may have had a previous breast surgery that has damaged the normal nerve pathways to the nipple, such as breast reduction or enlargement surgery. If you have altered sensation in your nipple after surgery (that is, your nipple is either somewhat numb or super-sensitive), it is possible that nerve damage from the procedure could interfere with your let-down reflex.

What can I do to improve my milk flow?

The following suggestions can help trigger the let-down reflex and improve milk flow:

  • Try to nurse or pump in a place that is familiar, comfortable, and restful.
  • Drink a beverage whenever you sit down to nurse or pump.
  • Play soft music or do relaxation exercises before you nurse or pump.
  • Gently massage your breasts before you nurse or pump.
  • Have your partner give you a backrub before you nurse or pump.
  • Put a warm washcloth or heating pad on your breasts, or take a warm shower before you nurse or pump.
  • If you are pumping because you are separated from your baby, put a photograph of your baby by the pump.

Are there medical alternatives to improve my milk flow?

A synthetic (man-made) form of oxytocin was formerly marketed as a nasal spray known as Syntocinon. The drug was sometimes prescribed for mothers of premature infants who needed help conditioning their let-down reflex when using a breast pump. Syntocinon is no longer on the market. However, a compounding pharmacist can make the same drug with a prescription from your health care provider.

Why feeding your baby will NOT make your breasts sag

Breastfeeding does not make the bust sag, according to scientists.

A study has shown that smoking and ageing both affect how pert the breast remains - as does pregnancy itself.

But feeding a baby for around nine months will not add to the droop.

Experts hope the news will encourage more mothers to breastfeed and take advantage of the health benefits for their children.

Plastic surgeon Brian Rinker said he was inspired to carry out the study after hearing many of his patients blame their saggy breasts on breastfeeding.

He and his team interviewed 132 women seeking breast lifts or augmentation between 1998 and 2006 - 93 per cent of whom had experienced at least one pregnancy.

Among the mothers, 58 per cent had breastfed at least one child, for an average of nine months.

The researchers evaluated the womens' medical history, body mass index, pre-pregnancy bra cup size and whether or not they smoked.

There was no difference found in the degree of breast ptosis - sagging - between women who breastfed and those who did not.

But smoking was found to have an effect, according to Dr Rinker. He said that smoking breaks down a protein in the skin called elastin, which makes skin look young and supports the breast.

He added that pregnancy has a 'very strong contribution to breast ptosis' and that the negative effects increase with each child.

Dr Rinker, from the University of Kentucky, said: "Women may be reluctant to breastfeed because of this unfounded myth that doing so means the end of youthful breasts.

"A lot of times, if a woman comes in for a breast lift or a breast augmentation, she'll say 'I want to fix what breastfeeding did to my breasts'".

"Now, expectant mothers can relax knowing that breastfeeding does not sacrifice the appearance of their breasts."

The results of the study were presented at a conference of the American Society of Plastic Surgeons.

They follow research showing that breastfeeding makes babies brainier.

British researchers discovered that mother's milk in the first few months of life can boost a child's IQ by seven points.

This applies in nine cases out of ten, where the youngster inherits a common but newlyidentified 'brain-boosting' gene.

Britain has one of the lowest rates of breastfeeding in Europe.

Around a fifth of women choose not to, while a third of those who do try will give up within six months.

Breast-feeding is best for a brainy baby

says study..

Breast-feeding really does make babies brainier, a major study suggests.

British researchers have found that mother's milk in the first few months of life can boost children's IQ by seven points.

This applies in nine cases out of ten, where the youngster inherits a common but newly-identified "brain boosting" gene.

The finding adds to the mounting evidence that breast-fed babies are happier, healthier and brighter than those raised on formula milk.

It also helps resolve a long-running dispute about the benefits of breast milk on intelligence - and the role of nature and nurture in IQ.

The findings were welcomed by health campaigners, who say that Britain has one of the lowest rates of breastfeeding in Europe and that too little is done to support and encourage new mothers.

Around a fifth of women choose not to breast feed their babies, while a third of those who do have given up within six months.

The link between breast milk and intelligence was first discovered in 1929 and is often used as an incentive to encourage mothers to feed naturally.

However, a major study by the Medical Research Council last year suggested that the link was a myth.

It found that past research had failed to take into account the mother's background.

Not only were those who breastfeed usually brighter, they were more highly educated, older, better off and provided a more stimulating home environment, it found.

Now two studies suggest that breast milk helps babies whatever their family background.

In one, carried out on 1,037 children in New Zealand, IQ was tested at ages seven, nine, 11 and 13.

DNA samples were gathered from the participants when they reached 18.

The other study looked at 2,232 British twins, whose IQ was measured at five.

Both sets of research found that the IQs of breastfed children were seven points higher, even after their social background was taken into account - so long as they had inherited a particular gene from their parents.

The gene, FADS2, is involved in the way the body processes fatty acids in the diet.

Breastfeeding made no difference to the one in ten children who did not carry the gene variant, according to a team from King's College, London.

Previous research has shown that longchain polyunsaturated fatty acids (Pufas) accumulate in the brain during the months after birth.

They are present in human breast milk, but not cow's milk, and have recently been added to infant formulas.

Pufas are thought to be important to childhood brain development because they are essential for the efficient transmission of nerve messages and help to promote the growth of nerve fibres.

The findings appear in the journal Proceedings of the National Academy of Sciences. Professor Terrie Moffitt, based at the Institute of Psychiatry in London, said: "The argument about intelligence has been about nature versus nurture for at least a century. We're finding that nature and nurture work together.

"Our findings support the idea that the nutritional content of breast milk accounts for the differences seen in human IQ. But it's not a simple allornone connection: it depends to some extent on the genetic makeup of each infant."

In the last decade, many infant formula makers have started adding two Pufas - docosahexaenoic acid (DHA) and arachidonic acid (AA) to their products.

But the children taking part in the gene study were born in 1972-73 in New Zealand and 1994-95 in England, before fatty acid supplementation of infant formula began.

The jury is still out on whether Pufa supplementation has made a difference. However, in laboratory tests, animals given fatty acid supplements have performed better at learning, memory and problem-solving tests.

Past studies have shown that breast-fed babies are less likely to suffer from asthma, eczema, heart disease and obesity later in life.

Rosie Doddes, a breastfeeding adviser for the National Childbirth Trust, said the benefits of breastfeeding to mothers and children were well established.

"In the early months, breastfeeding protects against respiratory and gastrointestinal problems.

"It's up to women to choose whether to breast feed or bottle feed, but we are very concerned that women are not getting the right support and information.

"Rates are relatively low in Britain compared to Europe, and very low compared with the rest of the world."
