济南家政http://www.woai-wojia.com/谈到有一些家长总想给孩子早一点添加辅食，似乎早一点添加辅食孩子就会越吃越壮，但是过早添加辅食对孩子害处多多，这是因为小婴儿胃肠道发育还不成熟。
Jinan housekeeping always want to talk about some parents give their children a little early complementary feeding, it seems a little early complementary feeding the child will eat more strong, but too early complementary feeding a lot of harm to the child, it is because the baby gastrointestinal development is not mature.

济南家政建议应在婴儿满6个月时再添加辅食，因为肠粘膜屏障包括它的物理性保护机制以及肠淋巴组织、分泌性免疫球蛋白细胞免疫的免疫性保护机制，要到婴儿6个月时才能发育完善。因此，在出生后的头几个月中，婴儿肠道的通透性较大，一直持续到婴儿3～4个月时。而且消化酶系统也发育不成熟，造成进入体内的蛋白质未充分分解即吸收入血，引起胃肠道过敏反应。小婴儿又缺乏分布于肠粘膜表面的保护性抗体——分泌性免疫球蛋白A，缺乏此类抗体可使肠道细菌在粘膜表面造成炎症，这样便加速了肠粘膜对异种蛋白吸收，诱发胃肠道过敏反应。同时再伴以较大的肠道通透性，使得婴儿容易发生过敏。一小口食品中的抗原量可能是母乳中同种抗原的1000倍。因此根据世界卫生组织的建议婴儿6个月以后再添加辅食，尤其对于有过敏倾向的家族史的孩子。
Jinan domestic proposals should be complementary feeding in infants over six months, because mucosal barrier, including its physical protection mechanisms and intestinal lymphoid tissue, immune protection mechanisms of secretory immunoglobulin cellular immunity to the baby 6 months perfect time to develop. Thus, in the first few months after birth, the infant intestinal permeability larger lasted three to four months a baby when to. But also immature digestive enzyme system, resulting in a protein into the body that is absorbed into the bloodstream is not fully decomposed, cause gastrointestinal allergic reactions. Baby and lack of distribution in intestinal surface protective antibodies -secretory immunoglobulin A, the lack of such antibodies can cause inflammation of the intestinal bacteria in the mucosal surface, thus accelerating the intestinal absorption of foreign proteins, induced gastric intestinal allergies. At the same time again accompanied by large intestinal permeability, making the baby prone to allergies. A small mouth food may be 1000 times the amount of antigen in breast milk alloantigens. So then add complementary according to World Health Organization's recommended for infants 6 months later, especially for a family history of allergy-prone children.

济南家政介绍小婴儿唾液腺分泌相对的少，4个月才开始逐渐增加，5～6个月分泌量增多，唾液具有消化和抑制细菌生长的作用，同时唾液还有消化酶，主要是淀粉酶分泌增加，能对食物进行初步的消化作用。
Jinan housekeeping introduce baby salivary secretion is relatively less, began to gradually increase four months, an increase of 5 to 6 months secretion, saliva has digestive and inhibit the growth of bacteria, and saliva as well as digestive enzymes, mainly amylase secretion increase, able to preliminary digestion of food.

济南家政http://www.woai-wojia.com/提醒根据孩子生理发育的特点是不能早添加辅食的，当然每个孩子发育是有差异的。如果你的孩子已经完全具备添加辅食的条件就可以添加了，但是最早不能早于4个月，最晚不能晚于8个月。
Jinan housekeeping remind according to the child's physical development is characterized by early complementary feeding can not, of course, there is every child developmental differences. If your child has been fully equipped with complementary feeding conditions can be added, but not earlier than the first four months, the latest no later than eight months.
