"Sleep yellow in January, cry intestines in February, save your stomach in March and April", which is a formula about baby growth. Newborns spend most of their time sleeping in the first month after birth, because their brains and bodies are still developing and need a lot of rest. In the second month, babies begin to have more feelings and emotions, and may cry. This is because their gastrointestinal function is not mature enough and they are prone to indigestion. In the third month, the baby's gastrointestinal function gradually matures, but constipation may occur, because their intestines are still developing and it takes some time to adapt. In the fourth month, the baby's gastrointestinal function has basically matured, but they may begin to have anorexia, because their taste is developing and their acceptance of food is changing.
Although this formula is simple, it contains a lot of knowledge about baby growth. According to this formula, parents can understand the needs of their babies at different stages, so as to take better care of them. For example, for the first-month children, parents need to ensure that they have enough sleep; For children of the second month, parents need to pay attention to their diet to avoid indigestion; For the children of the third month, parents can give them some abdominal massage appropriately to help them relieve constipation; For the fourth month children, parents can try to provide them with different foods to help them establish good eating habits.
