Starting solids spinoff - why 6 months?

I've read on here a lot that the new recommendations are for waiting until 6 months to start solids. DS's ped GI doc and his regular ped told us at his appointments this week that we should start solids. (ETA: DS is 4.5 months)

He's been having a bit of rice cereal in his bottles for a month because of reflux and has been doing SO well since we started that.

I wanted to wait until 6 months to start spoon feeding him solids, partly because I feel like we JUST got him on a feeding routine that works for him and doesn't make him throw up like crazy, and partly because I'm lazy But with both doctors telling us to start and my mom and my MIL chiming in that we should start feeding him solids, DH thinks we should try and I'm willing to give it a go and see.

But what's the reason for waiting until 6 months now? Is there somewhere I can read up more about why?

Reasons for delaying solids

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.

* 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 contains 50+ 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 and Risks of Artificial Feeding).

* 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 and Risks of Artificial Feeding). 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 from other 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.

Thanks Hayley! DS is BF and also FF (supply issues) so I'm curious if that makes anything different.

Re: Starting solids spinoff - why 6 months?

From what I've read, there's basically "literature" saying 6 months is too late and too early... this is another one where I think you have to decide for yourself and your child. My DD has a milk protein allergy and terrible reflux - it's under control now but it took a long time for us to get there on the reflux. Solids generally help with reflux so we pretty much started at the 4-month mark - she's been doing great on solids, our ped has us wait 5 days per new food to see if there are reactions, and I just added a second solid meal today - she's almost 6 months now - since she seems a little hungry the last couple of days - she's very eagerly gulping down her bottles, which is rather unlike her. Solids are still not her primary source of nutrition - up until today, she's had one solid meal a day - but given her reflux and given her excitement about watching us eat, I felt it was time and it's been going great. FWIW, I don't read studies, but I've seen dozens of news articles going back on forth on this, esp as relates to food allergies and I think the truth is that no one really knows the effects one way or the other and the studies are actually pretty inconsistent so that's why recommendations seem to change on practically a weekly basis.

Re: Starting solids spinoff - why 6 months?

The "new" AAP recommendation is 4-6 months, leaving a lot of leeway as there is a lot of disagreement among experts, as well as on this board (if you've noticed)

There is a growing belief that starting solids too late, is actually what is causing the rise of food allergies in children.

There was a recent (Jan 2010) Finnish study that concluded, that late introduction of solid foods was associated with increased risk of allergic sensitization to food and inhalant allergens.

AAP refers to it in its most recent recommendations of starting solids 4-6 months.
