Many parents pay special attention to baby products, because if there is any adverse effect on the baby, it will be distressed. Diapers are a baby's daily necessities and are used in a large amount. In order to solve the doubts of parents, let's answer them below. Do babies wear diapers? Will it cause O-shaped legs? There are many factors that cause O-shaped legs, but it is mainly caused by the lack of calcium in the baby's own body, which has nothing to do with the use of diapers. However, it is worth noting that if the baby’s diapers are not changed in time, the longer the time, the more urine will flow to the left and right sides of the diaper to expand. At this time, the baby’s legs will involuntarily expand outward. The awareness that the inner thighs expand outward will not only affect future walking, but also hinder the baby's bone development. Therefore, parents can buy diapers that expand in the front and rear directions. Do babies wear diapers? Will it affect the baby's ability to hold back urine? Under normal circumstances, babies usually have to control their bowel movements and urination freely until they are around 3 years old, but before that, especially before one and a half years old, the baby's ability to control bowel and bowel movements is Very limited, this is because the infant’s brain function development is not yet perfect, and its ability to inhibit the basic urination center is weak, and the urethral sphincter and anal sphincter that control bowel and urination have not yet matured. In other words, even if you don't wear diapers, your baby still has to pee because these are all determined by the baby's physical development. As many other mothers have said, if you urinate successfully, it is not that the baby will hold back the urine, it may just be because you have found the time for the baby to urinate.
