The height and weight standards for 3-month-old babies should be combined with individual children to make a comprehensive judgment. The normal height range for 3-month-old babies is 57.1 to 63.7 cm, and the normal weight range is 4.7 to 6.9 kg.
1. Male babies, at the 3-month stage, the normal range of height for male babies is 58.5 to 63.7cm and the standard range of weight is 5.0 to 6.9kg.
2. Female babies, at the 3-month stage, the normal range of height for female babies is 57.1-59.5cm, and the standard range of weight is 4.7-6.2kg.
Children’s height and weight do not increase at a uniform rate, so it is recommended that when evaluating a baby’s level of growth and development, it should be based on changes in the individual child, and it is not appropriate to take the normal range as a standard for evaluation. Regular medical check-ups for children are important.
