If the height of a 3-week-old male baby is 95cm, it is slightly short, and the standard height of a 3-week-old male baby is 96.8cm, which corresponds to a weight of 14.65kg. if it is slightly short, a comprehensive analysis should be made. If the baby’s length at birth is relatively short and below normal, the child’s height may be slightly shorter at 3 weeks of age. If the child eats poorly and has a poor appetite, the child’s length may be affected. If there is a deficiency of calcium, iron and zinc in the baby’s trace elements, and at the same time the child’s immune function is relatively poor, it will affect the baby’s absorption and will affect the child’s height. When the height belongs to the level of slightly short, it is necessary to analyze comprehensively what exactly is caused by it and give further adjustment.
