小革命
小革命
阿土仔马上一岁了,还不走路,事实上,他还不自己站呢。虽然阿土仔妈其实挺高兴他自主运动能力有限,但是咱也不能太落后了,所以最近经常让他在厅里地板格上站站拉着他走走。小家伙自己倾向于当爬行动物,重心放在屁股上,站一会儿腿儿一软,吧唧一下儿就坐那儿了,然后就一翻身蹭蹭蹭开爬。阿土仔妈也就由他去,自己上网玩耍。
不过这个实在是对阿土仔妈神经的考验。因为阿土仔非常善于发掘掉在地上的丁点儿东西,然后就放嘴里。好比今天下午,阿土仔睡醒下午觉,给阿土仔妈牵着走到厅里,坐地上了。阿土仔妈打开电脑,看一会儿电脑,看一眼阿土仔,啊,在那儿敲东西呢,不理他。过一会儿阿土仔爬过来,扒着阿土仔妈的腿站着,伸长了脖子看妈妈在看啥。看了一会儿觉得没意思,爬到阿土仔妈脚底下,写字台放腿的空档里。阿土仔妈弯腰探头看了看,小家伙正在舔阿土仔妈收藏的CD,继续不理他。不一会儿该吃饭了,阿土仔妈给小家伙开了个罐头,小家伙坐在高椅里很期待的等着。阿土仔妈第一小勺先把粘在罐头盖儿上的糊糊刮下来,往他嘴里送。小家伙嚼着东西张大了嘴等着,我一看,他舌头上赫然一黑乎乎的不知道什么东西。我一下子急了,马上伸手进他嘴里去掏,没掏出来。马上把他给解下来仰面放我腿上,掐着他腮继续掏。没想到这孩子如同保护联络本儿的革命者,一仰脖儿,把嘴里东西咽下去了!
饶是阿土仔妈的坚强神经笃信“不干不净吃了没病”,也受不了这样儿的考验了。在阿土仔今天晚上睡着了之后打了桶水,水里挤了洗涤灵,趴在地上用纸抹布把厅里地板格一个格子一个格子的都擦了一遍。

乡音无改鬓毛衰
学会走路以后小东西就不乱检地下的东西吃了么?豪情 wrote:抱歉, 我们宝宝会坐爬到走路才一个月, 所以很快. 每个孩子都不一样, 不过都会过去的.
我朋友的两个宝宝一样年纪(俩朋友啊),都是十个月,女宝宝已经会走路了,男宝宝还只会爬。上周末在我家派对上见了面,女宝宝很热情,看见男宝宝就迅速的扑了上去,抱着他亲了一口。男宝宝吓到了,转身爬走,但是女宝宝走的比爬快,跌跌撞撞的跟了上去。。。。两个小东西在我的公寓里满地乱滚,太可爱了。我跟人说着话,觉的脚下痒,低头一看,俩宝宝的胖手指在鲜红色的高跟鞋上摸啊抓啊的,我直怕他俩上嘴就咬一口。

有事找我请发站内消息

Babies Know: A Little Dirt Is Good for You
By JANE E. BRODY
Ask mothers why babies are constantly picking things up from the floor or ground and putting them in their mouths, and chances are they’ll say that it’s instinctive ― that that’s how babies explore the world. But why the mouth, when sight, hearing, touch and even scent are far better at identifying things?
When my young sons were exploring the streets of Brooklyn, I couldn’t help but wonder how good crushed rock or dried dog droppings could taste when delicious mashed potatoes were routinely rejected.
Since all instinctive behaviors have an evolutionary advantage or they would not have been retained for millions of years, chances are that this one too has helped us survive as a species. And, indeed, accumulating evidence strongly suggests that eating dirt is good for you.
In studies of what is called the hygiene hypothesis, researchers are concluding that organisms like the millions of bacteria, viruses and especially worms that enter the body along with “dirt” spur the development of a healthy immune system. Several continuing studies suggest that worms may help to redirect an immune system that has gone awry and resulted in autoimmune disorders, allergies and asthma.
These studies, along with epidemiological observations, seem to explain why immune system disorders like multiple sclerosis, Type 1 diabetes, inflammatory bowel disease, asthma and allergies have risen significantly in the United States and other developed countries.
Training the Immune System
“What a child is doing when he puts things in his mouth is allowing his immune response to explore his environment,” Mary Ruebush, a microbiology and immunology instructor, wrote in her new book, “Why Dirt Is Good” (Kaplan). “Not only does this allow for ‘practice’ of immune responses, which will be necessary for protection, but it also plays a critical role in teaching the immature immune response what is best ignored.”
One leading researcher, Dr. Joel V. Weinstock, the director of gastroenterology and hepatology at Tufts Medical Center in Boston, said in an interview that the immune system at birth “is like an unprogrammed computer. It needs instruction.”
He said that public health measures like cleaning up contaminated water and food have saved the lives of countless children, but they “also eliminated exposure to many organisms that are probably good for us.”
“Children raised in an ultraclean environment,” he added, “are not being exposed to organisms that help them develop appropriate immune regulatory circuits.”
Studies he has conducted with Dr. David Elliott, a gastroenterologist and immunologist at the University of Iowa, indicate that intestinal worms, which have been all but eliminated in developed countries, are “likely to be the biggest player” in regulating the immune system to respond appropriately, Dr. Elliott said in an interview. He added that bacterial and viral infections seem to influence the immune system in the same way, but not as forcefully.
Most worms are harmless, especially in well-nourished people, Dr. Weinstock said.
“There are very few diseases that people get from worms,” he said. “Humans have adapted to the presence of most of them.”
Worms for Health
In studies in mice, Dr. Weinstock and Dr. Elliott have used worms to both prevent and reverse autoimmune disease. Dr. Elliott said that in Argentina, researchers found that patients with multiple sclerosis who were infected with the human whipworm had milder cases and fewer flare-ups of their disease over a period of four and a half years. At the University of Wisconsin, Madison, Dr. John Fleming, a neurologist, is testing whether the pig whipworm can temper the effects of multiple sclerosis.
In Gambia, the eradication of worms in some villages led to children’s having increased skin reactions to allergens, Dr. Elliott said. And pig whipworms, which reside only briefly in the human intestinal tract, have had “good effects” in treating the inflammatory bowel diseases, Crohn’s disease and ulcerative colitis, he said.
How may worms affect the immune system? Dr. Elliott explained that immune regulation is now known to be more complex than scientists thought when the hygiene hypothesis was first introduced by a British epidemiologist, David P. Strachan, in 1989. Dr. Strachan noted an association between large family size and reduced rates of asthma and allergies. Immunologists now recognize a four-point response system of helper T cells: Th 1, Th 2, Th 17 and regulatory T cells. Th 1 inhibits Th 2 and Th 17; Th 2 inhibits Th 1 and Th 17; and regulatory T cells inhibit all three, Dr. Elliott said.
“A lot of inflammatory diseases ― multiple sclerosis, Crohn’s disease, ulcerative colitis and asthma ― are due to the activity of Th 17,” he explained. “If you infect mice with worms, Th 17 drops dramatically, and the activity of regulatory T cells is augmented.”
In answer to the question, “Are we too clean?” Dr. Elliott said: “Dirtiness comes with a price. But cleanliness comes with a price, too. We’re not proposing a return to the germ-filled environment of the 1850s. But if we properly understand how organisms in the environment protect us, maybe we can give a vaccine or mimic their effects with some innocuous stimulus.”
Wash in Moderation
Dr. Ruebush, the “Why Dirt Is Good” author, does not suggest a return to filth, either. But she correctly points out that bacteria are everywhere: on us, in us and all around us. Most of these micro-organisms cause no problem, and many, like the ones that normally live in the digestive tract and produce life-sustaining nutrients, are essential to good health.
“The typical human probably harbors some 90 trillion microbes,” she wrote. “The very fact that you have so many microbes of so many different kinds is what keeps you healthy most of the time.”
Dr. Ruebush deplores the current fetish for the hundreds of antibacterial products that convey a false sense of security and may actually foster the development of antibiotic-resistant, disease-causing bacteria. Plain soap and water are all that are needed to become clean, she noted.
“I certainly recommend washing your hands after using the bathroom, before eating, after changing a diaper, before and after handling food,” and whenever they’re visibly soiled, she wrote. When no running water is available and cleaning hands is essential, she suggests an alcohol-based hand sanitizer.
Dr. Weinstock goes even further. “Children should be allowed to go barefoot in the dirt, play in the dirt, and not have to wash their hands when they come in to eat,” he said. He and Dr. Elliott pointed out that children who grow up on farms and are frequently exposed to worms and other organisms from farm animals are much less likely to develop allergies and autoimmune diseases.
Also helpful, he said, is to “let kids have two dogs and a cat,” which will expose them to intestinal worms that can promote a healthy immune system.
