For infants and young children, most young mothers have reported that the most common problem is that baby bottles are often heated and disinfected, and colored patterns printed on baby bottles, especially the scales on the surface of the bottles, will fade after being used for a period of time. Drop it. The scale is worn and it is not easy to grasp the amount of breast milk. Young mothers also worry that these color patterns will not affect children's health. However, the problem of "scale" differences has not attracted enough attention.
Bottle scale, details can not be ignoredBut it is precisely this often neglected number of ticks that may have an important impact on the health of infants and young children.
Bottle scale differences
Ms. Duan, who works at a Magazine in Beijing, stated that her baby mainly eats milk powder after weaning. Once she stumbled upon the difference in the number of ticks between the two bottles. In order to clarify this issue, she started a friend with a little baby around and asked them to pour the same amount of water into different bottles to see if the bottle scale was the same. Six of the 18 bottles were different. Among them, the smallest difference is about 5 ml, and the most difference is about 30 ml. If(window.location.href.getQueryString("ip")==null) Loc=sohu_IP_Loc.substr(0,4); else Loc=window.location.href.getQueryString("ip"); Ms. Duan worried, so How can I have no effect on my child's growth and development after a meal of hunger?
In order to verify Ms. Duan’s words, we compared two bottles with the same volume and different brands, and injected the same amount of fresh water. One scale showed 20 ml, and the other showed 17.5 ml.
What is the exact number of ticks on these two bottles? How can the difference in scales affect the infants and young children who rely on milk powder to provide nutrition?
Dr. Wang Dafu, a child care practitioner at the Third Affiliated Hospital of Peking University, introduced: The bottles on the market are mostly 80ml, 120ml, 160ml, 200ml, 240ml, etc. The volume scale is marked on the bottle to facilitate the parents to master the infant's food intake. It is conducive to scientific childcare. Due to the lack of breast milk, infants who must be mixed or artificially fed, mostly choose to replace dairy products such as formula milk powder. Such children mainly rely on milk powder to provide all the nutrition. If the difference is 10ml once, then it will be 40ml a day, and the difference will be 40ml. Eating more is obviously detrimental to your child's health. Therefore, the scale on the bottle must be measured accurately.
Bottles with scales count as a measuring instrument
According to the AQSIQ metrology and measurement staff, the measurement instrument as a special product is an important measure for achieving unity of value, such as scales, electricity meters, and water meters. The bottle is an ordinary container, although it has a scale, but it does not belong to the measurement apparatus, so it is not included in nor can be included in the "National Catalogue of Measurement Instruments Managed by Law", so it does not fall within the scope of the directory management.
Zhang Jingyu, chairman of the China Weighing Apparatus Association, said: The bottle scale is not accurate, it is difficult to grasp the amount of sucking milk for infants and young children, the growth and development of infants and children are unfavorable. As the scale “shrinksâ€, protein, fat, heat, etc. in milk powder will be reduced accordingly, and the nutrition that children receive will be reduced. If parents inadvertently purchase inferior milk powder and have insufficient protein, then it will have a greater impact on the health of the child. He believes that in general, there are errors in the scale of the bottle. The question is how much the error is tolerable.
Therefore, Zhang Jingyu urged that manufacturers should pay attention to such issues and strictly measure to ensure that the bottle size is precise and accurate. In addition, the plastic milk bottle has a problem of thermal expansion and contraction, which is affected by the temperature, and the factors such as the shrinkage factor, capacity coefficient, and chemical composition, etc., manufacturers should fully consider.
Some experts warn that, like some household body scales, the data they display is not necessarily accurate, and the scale on the bottle is the same. Therefore, given that some parents are accustomed to using bottles to feed their children, it is not necessary to rely on the scale on the bottle when determining the dose of the infant.
