Baby & Health- Is Feeding Bottles Safe?


Baby & Health- Glass vs. Plastic Baby Bottles


Decades ago, the only baby bottles available to parents were made of glass. But glass was heavy and, more importantly, breakable. So when plastic bottles came along that were lighter and shatter-proof, the glass bottle became almost obsolete.
However, recent reports that a type of plastic found in baby bottles might cause potentially harmful changes in developing babies has left parents wondering if perhaps old-fashioned glass wasn't such a bad thing after all.


Baby Bottle Worries

The problem with glass bottles is pretty obvious -- drop one on the floor in the middle of a late-night feeding, and you'll have a roomful of shattered glass to clean up. Glass is also heavy and cumbersome. On the upside, glass bottles are sturdy, and they don't contain any chemicals that could potentially get into the baby's formula.
Plastic baby bottles are lightweight, strong, and unbreakable. However, concerns have arisen about the polycarbonate type of plastic bottles because they contain a chemical called bisphenol A (also called BPA). Bisphenol A is also used in everything from compact discs to the lining of cans, as well as other consumer products. A 2007 report by the organization Environment California showed that when heated, five popular brands of BPA-containing plastic baby bottles leached high levels of bisphenol A.
In studies of lab rats, low levels of BPA were linked to changes in the brain and reproductive system that researchers say may contribute to an increased risk of prostate and breast cancers, ovarian cysts, endometriosis, and early puberty.
Before you panic, know that government health officials don't believe that the amount of BPA in baby bottles and other consumer products is dangerous. After reviewing research on the plastic, the FDA stated that based on its ongoing review it believes the amounts of bisphenol A that find their way into food and drinks are too low to cause any real health effects in humans. However, the agency is continuing to look into the question of BPA safety, and for now, the issue remains unresolved.

Choosing a Baby Bottle

There are essentially three types of baby bottles: plastic, plastic with disposable liners, and glass.
Although the jury is still out on bisphenol A, if you want to avoid any bottles that contain it, look for the #7 recycling symbol or "PC" on the bottom. That's usually a sign that the bottle contains BPA. However, not all plastics labeled with #7 recycling code contain BPA. Some bottle brands, such as Born Free, explicitly say that their products are not made of Bisphenol A.
The six major U.S. manufacturers of baby bottles and infant feeding cups have confirmed to the FDA that as of January 2009, they have not manufactured these products using BPA for the U.S. market.  These manufacturers represent more than 90% of the U.S. market.  These manufacturers produce brands that include Avent, Doctor Brown’s Natural Flow, Evenflow, First Essentials, Gerber, Munchkin, Nuk, and Playtex.    
Even if you're concerned about bisphenol A, you don't have to give up your plastic bottles. Non-polycarbonate plastic versions are available. They're made of polyethylene (#1, #2, or #4 recycling symbols) or polypropylene (#5 recycling symbol). Non-polycarbonate plastics are also options when your child graduates to a sippy cup.
Disposable bottle liners are also typically BPA-free (look for the words "BPA-free" on the label). They tend to be more expensive than bottles alone, though, because you have to change them after each feeding.
If you want to try glass bottles but you're concerned about them breaking, some companies make silicone sleeves that go over the bottle to protect it.
Caring for Your Child's Baby Bottle
Here are some tips on caring for your child's baby bottle and reducing potential risks from BPA:
·         Never store breast milk or formula in plastic bottles. Pour it into the bottle just before your baby is ready to eat. Throw out anything that is left over.
·         Heat and wear can both increase the rate at which BPA leaches out of the plastic. Heat polycarbonate bottles in warm water (not boiling), rather than in the microwave. Microwaves should also be avoided because of the risk of burning baby's mouth. Throw out any polycarbonate bottles that are scratched or cracked.
·         Don't use hot water or a harsh cleaner on polycarbonate bottles because this also can cause the plastic to break down more quickly. Instead, use a gentle cleaner and warm water.
·         Replace any glass bottles that have cracks or chips in them.

Keep in mind that bisphenol A is also found in the linings of formula cans and can get into the product. You might want to opt for powdered formulas, which typically contain lower levels of BPA than liquid formulas.

Appetite Loss in Toddlers, Reasons and Solutions

Appetite Loss in Toddlers
Feeding a toddler can be a challenge. Seemingly overnight, your good little eater turns into Mr. Picky. As you watch him push away foods that used to be favorites, turn up his nose at anything green and absolutely refuse to try anything new, you wonder if he can really survive on what seems like a handful of food each day. Most of the time, a decrease in appetite in toddlerhood is normal, but if your child is pale, lethargic or tired all the time, sees his doctor.
Why Appetite Drops A toddler doesn't need to eat as much or as often as he did as an infant. His appetite drops because his growth rate slows. If he kept up the growth rate of the first year, when he tripled his weight and doubled his height, he'd be around 60 pounds and 5 feet tall at age 2. Since he'll grow just 3 inches and gain 3 to 5 pounds between the ages of 1 and 2, his appetite will decrease. To achieve this gain, he needs to consume between 1,000 to 1,400 calories per day, accordi…

How many calories one should eat !

The number ofcalories you should eat each day depends on several factors, including your age, size, height, sex, lifestyle, and overall general health. A physically active 6ft 2in male, aged 22 years, requires considerably more calories than a 5ft 2ins sedentary woman in her 70s. How many calories do I need per day? The Harris-Benedict equation, also known as the Harris-Benedict principle, is used to estimate what a person's BMR (basal metabolic rate) and daily requirements are. The person's BMR total is multiplied by another number which represents their level of physical activity. The resulting number is that person's recommended daily calorie intake in order to keep theirbody weightwhere it is.
This equation has limitations. It does not take into account varying levels of muscle mass to fat mass ratios - a very muscular person needs more calories, even when resting.

Hemophilia

HemophiliaIntroduction:

Hemophilia is an inherited disease in which your blood does not clot. People with hemophilia lack or have low levels of one of two blood-clotting substances, known as factor VIII and factor IX. As a result, they may bleed for a long time after an injury. They may also experience internal bleeding, especially in the joints. There are two types of hemophilia -- type A and type B. Hemophilia is the most common inherited bleeding disorder. About 17,000 people in the U.S. have the condition.

The blood of someone with hemophilia will not clot normally. Bleeding may occur spontaneously or followinginjury.Hemophiliaoccurs in 2 forms, hemophilia A and B. In both forms, a gene is defective. The defective gene interferes with the ability of the body to produce the clotting factors that allow for normal clotting. The result is a tendency for abnormal, excessive bleeding.
·  Hemophilia A occurs in 1 in 10,000 people. Hemophilia B occurs in 1 in 40,000.
