13-month-old babies can learn about their developmental standards in terms of height, weight, teeth, language and movement, which are analyzed as follows.
1. Height and weight: 13-month-old male babies are 75.0~80.4cm tall and weigh 9.14~11.24kg; female babies are 73.4~78.6cm tall and weigh 8.48~10.56kg.
2. Teeth: Most of the babies grow 8 milk teeth and grow mandibular lateral incisors.
3. Language and movement: some babies are able to walk independently, understand adult language, can speak with limited vocabulary, and will use movement and gestures to express their requirements. At this time the baby’s hands have been very developed, can do some relatively fine and precise movements, give him some toys that can be put into a large box, you can try to let him eat by himself with a spoon.
Every baby’s growth and development will be different, some development may be delayed for 1~2 months, which is also normal. If you find any abnormality, it is recommended that you seek medical advice promptly.
