Parents are very concerned about their baby's development, fearing that the baby's height, weight and other aspects do not meet certain standards. In fact, this worry is completely unnecessary, because each baby's physical fitness is different, some babies develop early and some babies develop at night, so parents must not be too nervous, as long as they provide a good living environment for the baby and keep him healthy.
