Baby Led Weaning or BLW

First things first, what is baby led weaning? "Baby Led Weaning, quite simply, means letting your child feed themselves from the very start of weaning*."  "In the UK, ‘weaning’ means ‘adding complementary foods’, whereas in the States it means ‘giving up breastfeeding’."-  babyledweaning.com

Reasons for delaying solids

Delaying solids gives baby greater protection from illness.

Although babies continue to receive many immunities from breastmilk for as long as they nurse, the greatest immunity occurs while a baby is exclusively breastfed. Breastmilk contains50+ known immune factors, and probably many more that are still unknown. One study has shown that babies who were exclusively breastfed for 4+ months had 40% fewer ear infections than breastfed babies whose diets were supplemented with other foods. The probability of respiratory illness occurring at any time during childhood is significantly reduced if the child is fed exclusively breast milk for at least 15 weeks and no solid foods are introduced during this time. (Wilson, 1998) Many other studies have also linked the degree of exclusivity of breastfeeding to enhanced health benefits (see Immune factors in human milk).

Delaying solids gives baby’s digestive system time to mature. 

If solids are started before a baby’s system is ready to handle them, they are poorly digested and may cause unpleasant reactions (digestive upset, gas, constipation, etc.). Protein digestion is incomplete in infancy. Gastric acid and pepsin are secreted at birth and increase toward adult values over the following 3 to 4 months. The pancreatic enzyme amylase does not reach adequate levels for digestion of starches until around 6 months, and carbohydrate enzymes such as maltase, isomaltase, and sucrase do not reach adult levels until around 7 months. Young infants also have low levels of lipase and bile salts, so fat digestion does not reach adult levels until 6-9 months.

Delaying solids decreases the risk of food allergies.
 
It is well documented that prolonged exclusive breastfeeding results in a lower incidence of food allergies (see Allergy References). From birth until somewhere between four and six months of age, babies possess what is often referred to as an “open gut.” This means that the spaces between the cells of the small intestines will readily allow intact macromolecules, including whole proteins and pathogens, to pass directly into the bloodstream.This is great for your breastfed baby as it allows beneficial antibodies in breastmilk to pass more directly into baby’s bloodstream, but it also means that large proteins fromother foods (which may predispose baby to allergies) and disease-causing pathogens can pass right through, too. During baby’s first 4-6 months, while the gut is still “open,” antibodies (sIgA) from breastmilk coat baby’s digestive tract and provide passive immunity, reducing the likelihood of illness and allergic reactions before gut closure occurs. Baby starts producing these antibodies on his own at around 6 months, and gut closure should have occurred by this time also. See How Breast Milk Protects Newborns and The Case for the Virgin Gut for more on this subject.

Delaying solids helps to protect baby from iron-deficiency anemia.

The introduction of iron supplements and iron-fortified foods, particularly during the first six months, reduces the efficiency of baby’s iron absorption. Healthy, full-term infants who are breastfed exclusively for periods of 6-9 months have been shown to maintain normal hemoglobin values and normal iron stores. In one study (Pisacane, 1995), the researchers concluded that babies who were exclusively breastfed for 7 months (and were not give iron supplements or iron-fortified cereals) had significantly higher hemoglobin levels at one year than breastfed babies who received solid foods earlier than seven months. The researchers found no cases of anemia within the first year in babies breastfed exclusively for seven months and concluded that breastfeeding exclusively for seven months reduces the risk of anemia. See Is Iron-Supplementation Necessary? for more information.
Delaying solids helps to protect baby from future obesity.

The early introduction of solids is associated with increased body fat and weight in childhood. (for example, see Wilson 1998, von Kries 1999, Kalies 2005)

Delaying solids helps mom to maintain her milk supply.
 
Studies have shown that for a young baby solids replace milk in a baby’s diet – they do not add to baby’s total intake. The more solids that baby eats, the less milk he takes from mom, and less milk taken from mom means less milk production. Babies who eat lots of solids or who start solids early tend to wean prematurely.

Delaying solids helps to space babies.

Breastfeeding is most effective in preventing pregnancy when your baby is exclusively breastfed and all of his nutritional and sucking needs are satisfied at the breast.

Delaying solids makes starting solids easier. 

Babies who start solids later can feed themselves and are not as likely to have allergic reactions to foods.
Most babies will become developmentally and physiologically ready to eat solids by 6-9 months of age. For some babies, delaying solids longer than six months can be a good thing; for example, some doctors may recommend delaying solids for 12 months if there is a family history of allergies.
Although some of the reasons listed here assume that your baby is breastfed or fed breastmilk only, experts recommend that solids be delayed for formula fed babies also.]

"after all is said and done, it pretty much comes down to this: There are no benefits, only risks, to starting a baby before they're biologically ready, and since we can't see the gut, we have to go by outside cues, and waiting until a bare minimum of 6 months is the safest way to play it. If a couple weeks is the difference between a gut infection and not, the choice is pretty clear." ---thestir.cafemom.com

I cut and pasted a lot of the science behind delaying solids because those were the same websites I read that helped solidify my decision to delay starting solids until 6 months and following through with baby led weaning. I am only a couple of weeks into BLW but I started with carrots steamed really soft he really liked them and only gagged one time. next we tried avocados cut into thick slices and he absolutely loved them! he probably ate 1/4 of the avocado in one sitting. Next was banana, I just handed him half, and he was sort of so-so about the whole thing, like he could take it or leave it which really surprised me because I had heard babies love bananas. Today he had some cantalope and let me tell you, I have never seen him demand another piece like he did with the cantalope.

Another awesome thing about baby led weaning is that you can save so much money! Seriously, who doesn't love saving money? If you don't you're in the wrong blog, dude/lady.
