The thicker the milk powder, the more nutritious, the baby more resistant to hunger, this statement is not true. On the contrary, it may also affect the baby’s gastrointestinal function. Therefore, it is recommended that parents follow the instructions and feed their babies on demand. Too thick milk powder contains more nutrients, after entering the baby’s intestinal tract, because the gastrointestinal tract function is not yet fully developed, so it will increase the extra burden of digestion, resulting in indigestion. Bloating, abdominal pain, spitting up, constipation or change in stool character may occur, and these abnormal problems will cause damage to the mucous membrane of the baby’s gastrointestinal tract, which is not conducive to the baby’s health. In addition, the frequent occurrence of these problems is likely to make the baby resistant to drinking milk, causing displeasure and crying, affecting feeding. Therefore, parents should carefully check the instructions before brewing milk powder, and strictly follow the instructions to brew according to a certain proportion. And avoid eating too much at one time, feeding on demand, in order to make the baby timely absorption of nutrients, to promote the healthy development of the body.
