How tall is a baby at 3 months old?

The health of babies is very important. Their development will be reflected in their lives and in some details, such as height and weight. So here I want to introduce to you the height of babies at 3 months old. I wonder how much you know about it, parents? I hope you know more about it, so that we can better observe our children! Let’s take a closer look with me!

1. The weight of a 90-day-old boy is 5.0-6.9 kg, the height is 58.5-63.7 cm, and the head circumference is 41.0 cm. The weight of a 90-day-old girl is 4.7-6.2 kg, the height is 57.1-59.5 cm, and the head circumference is 40.1 cm. The large muscles and movements of a 90-day-old baby: When lying on your back, the head is in the middle, not tilted to one side; when sitting, the head can be held upright. Small motor skills and adaptive abilities: Eyes can move flexibly from side to side, and the child can reach out to grab toys. Language development: Will turn head to look when hearing a sound or respond when hearing his own name; will make sounds of protest or acceptance when someone else holds him. Development of social skills: can laugh out loud: full of interest in the external environment. Characteristics of baby resistance: the immune system of a newborn baby has not yet been activated, but there are more maternal antibodies entering from the placenta, and the antibody level in the body is still relatively high. Therefore, babies born at full term rarely get sick before 3 months old.

2. 1. Boys: At 6 months old, the average height is 58.1 cm. Those taller than 63.2 cm are considered too tall, and those shorter than 52.9 cm are considered too short. At 3 months, the average height is 61.1 cm. Any height greater than 66.4 cm is considered too tall, and any height less than 55.8 cm is considered too short. 2. Girls: At 2 months old, the average height is 56.8 cm. If it is greater than 61.6 cm, it is too tall, and if it is less than 52.0 cm, it is too short. At 3 months, the average height is 59.5 cm. Any height greater than 64.5 cm is considered too tall, and any height less than 54.6 cm is considered too short.

3. Reference for infant height and weight standards:

1 month old male: height 48.2-52.8cm, weight: 3.6-5.0kg; female: height 47.7-52.0cm, weight: 2.7-3.6kg
