What are the developmental indicators of thirteen-month-old babies?

When the baby is 13 months old, many parents pay special attention to their baby's developmental indicators during this period. They want to fully understand the baby's developmental indicators to see whether their children are developing normally. The following is a comprehensive introduction. For many parents, they can have a specific understanding of the following content to see whether their baby is developing normally during this period.

Physical appearance and growth

Physical Standards:

Weight: 8.3-12.7 kg for boys; 7.6-11.9 kg for girls.

Height: 71.8-82.7 cm for boys; 69.8-81.2 cm for girls.

Head circumference: 47.11 cm for boys and 45.82 cm for girls.

Teeth: 8 deciduous teeth have grown.

Developmental rules:

Weight: The growth rate slows down after 1 year old, but still increases steadily. It will increase by 2.5 kg per year.

Height: Although the growth rate is slower than in infancy, it is still in the peak period of growth and development. Boys will grow 13 cm taller this year and girls 10 cm taller.

Head circumference: The growth rate is slower than that of height and weight, so that the body proportions become more balanced.

Anterior fontanelle: For some babies, its shape has closed, while for others, it can still be felt.

At this age, most babies can stand steadily on their own without the help of an adult, and can take steps forward and walk independently. However, before they have mastered the walking technique, their steps are always large and their posture is crooked. If mom or dad is not in front to support them, the baby may fall forward. When mom or dad holds their baby's hand, most babies can move forward relatively smoothly.

When babies are just learning to walk, most of them walk on tiptoe, and one foot may drag a little, like a limp. Some babies may have "inward-turned toes" or "outward-turned toes". These are not abnormal symptoms. As the baby walks more steadily, these phenomena will gradually disappear.

Most babies over 1 year old can crawl freely forward or backward in all directions. However, it is not uncommon for babies to not be able to crawl freely. Parents do not need to be anxious or worried. A baby crawling late does not mean developmental delay. It often happens that babies who start crawling late can stand and walk much earlier.

What are the developmental indicators of a thirteen-month-old baby? I believe that through the comprehensive introduction above, you have a comprehensive understanding of the baby's development during this period. After a comprehensive understanding, parents should compare their children's developmental indicators with the developmental indicators introduced above to see whether their children are developing normally.
