Babies are not allowed to eat chocolate because of the risk of enuresis. Chocolate may cause an allergic reaction in the baby’s body, causing the bladder wall to swell, reducing its capacity and the smooth muscle to become rough, thus causing the bladder to spasm. At the same time, this allergic reaction can cause babies to sleep too deeply, so that they cannot wake up in time even when they have a urine filling, bedwetting can occur, and eventually enuresis can develop. Should not chocolate and milk at the same time to the child to eat, some children are not particularly adequate nutrition, often in the milk to eat chocolate, this situation is not scientific. Because the calcium in milk and the oxalic acid in chocolate may form calcium oxalate after combining. Calcium oxalate is insoluble in water, if consumed over a long period of time, it may lead to baby’s hair dry and glossy, in addition, may also have diarrhea, and calcium deficiency and slow development. Chocolate contains a lot of sugar, fat, less protein, inorganic salts and vitamins, and no dietary fiber at all, which is not conducive to the health and growth of the baby. Only when the child’s physical exertion is relatively large, between meals can be appropriate to give the child a little chocolate supplement, but not eat too much.
