Newborns grow fastest in height and weight in the first 6 months of life. Entering the 7th month, the weight and height indicators will increase more slowly than in the previous stages.

1. How much does a 7 month old baby weigh?

You can measure your child's weight and height with very simple tools such as scales and rulers. For children under 24 months old, measure the lying length and from 24 months old, measure the standing height.
Below is a standard weight and height chart for babies in the first year of life. There will be many factors that make a child's weight slightly different, so mothers should not be too worried if the child's weight has not exceeded the allowable threshold.

The average weight of a full-term, healthy newborn at birth is about 3,000 grams (3kg). A healthy, normal child when eating enough needs will gain weight every month.
Based on the weight and height data table of the World Health Organization, the weight and height of a 7-month-old baby will meet the standards at:
For boys, the weight will reach: 8.3 kg and height reached 69.2. For girls, the weight is 7.6 kg and the height is 67.3.

2. Height of 7 month old baby

Currently, many mothers are only interested in the weight growth, but have not paid attention to the height growth of their children.
The average length of a newborn is about 50cm, the first 3 months the baby grows from 3-4.5cm/month, the next 3 months increase from 2-2.5cm/month, the next 3 months increase 2cm/month, the next 3 months Next increase from 1-1.5cm. When a baby is 1 year old, it is 1.5 times longer than at birth (75cm). Thus, when about 7 months old, the average boy will reach about 69.2 cm, the girl will be about 67.3 cm.
Parents should regularly monitor the child's weight and height. In case the child is overweight or underweight, is outside the permissible threshold, or even has not gained weight for 3 consecutive months, parents may need the support of a nutritionist for children to find out. take corrective action, or identify a problem, if any.

3. Factors affecting children's height - weight

A number of factors will cause a child's weight to be lower, or higher, than average. Understanding the factors that affect the development of children's physical health will help parents have a better parenting orientation not only during this very important first year of life.
Genetic factors The child born will inherit all the genetic characteristics of both parents, including height and weight. However, genetics is not everything. Some studies suggest that a child's height is usually only 23% affected by genetic factors.
Nutrition and living environment

Nutrition and living environment are factors that directly affect a child's development, including height and weight. Malnutrition can slow down physical development. It not only affects bone density and the strength of teeth, the size of organs in the body, but also delays the child's ability to develop. However, if adequate nutrition is provided again, the baby can catch up the development that he should have achieved before. Therefore, you need to provide enough nutrients for children in each stage.
For 7-month-old children, breast milk is still the main source of energy for children to develop well, at this stage, eating for children is still just learning to eat and learn about eating.
The mother still maintains breastfeeding about 600-700ml/day and alternates feeding with 2 solid meals. Baby can eat monosodium glutamate, then switch to eat more salty powder. In addition, mothers can process salty flour and add pork, fish, ... to the menu for children to eat solids to supplement nutrients.
Besides nutrition, other environmental factors such as climate, environmental pollution can also be the risk of slowing down the physical development process in children.

At the same time, the physiological development or reproductive health of children during puberty and adolescence is also disrupted and delayed.
Care and closeness of parents Research at the National Institute of Child Health and Human Development (USA) shows that the care of parents and non-blood relatives (who keep the same bloodline) child) is a major factor in the physical and mental, behavioral, and emotional development of a child from birth to puberty.
Maternal health during pregnancy and lactation Maternal health during pregnancy is directly related to the health and development of the fetus. If pregnant mothers are often stressed, or sick, poor nutrition can slow down the development of the baby.
For mothers who are breastfeeding, during this period, breast milk is still the main meal of the baby. Mothers must supplement with adequate nutrients for adequate milk supply, many nutrients to help children develop comprehensively.
