How many pounds does a newborn baby gain in one month?

Under normal circumstances, a newborn baby will gain 2-3 pounds in a month. For example, a full-term baby weighs 5-8 pounds when it is just born. However, because the baby needs to adapt to the new environment after birth, plus the excretion of meconium and the loss of water in the body, the weight gain standard of the baby within one month after birth is as follows. Take the baby as an example.

1. First 7 days: The baby's weight drops to 3%-9% compared to birth weight. If the baby's weight at birth is 6 catties, then the weight in the first 7 days will be 5.82-5.06 catties, and the weight will be the lowest on the 3rd-4th day after birth.

2. On the 7th to 10th day, the baby's weight returns to the level at birth, about 6 pounds.

3. On the 10th to 20th day, the weight increases to about 7 to 8 kilograms.

4. On the 20th to 30th day, the weight increases to about 8 to 9 kilograms.

Let the newborn baby gain normal weight

1. Feed more milk and less water

Some babies drink a lot of water while drinking milk, which can easily cause their stomachs to be occupied by water. Water has little nutrition and calories and cannot meet the baby's growth needs. Therefore, parents should ensure that the milk intake is sufficient and the baby's weight gains normally.

2. Mom’s diet should not be too greasy

It is best to remove the floating oil on the surface of the milk-inducing soup that mothers usually drink to prevent the baby from being overweight. In addition to eating some nutritious soups, you should also eat more vegetables and fruits to ensure a balanced nutrition and allow the baby to gain weight normally.

3. Adhere to exclusive breastfeeding

Breast milk is the best way of feeding. On the one hand, breast milk is more conducive to the baby's absorption and prevents the baby from being too light. On the other hand, babies fed with formula are prone to big heads, overweight, allergies and other phenomena. Therefore, insisting on breastfeeding can make the baby eat safely and healthily, and the weight gain will be standard.

4. Get some sun exposure

Babies will have some degree of neonatal jaundice after birth. Taking your baby out to bask in the sun properly will not only help the jaundice disappear, but also promote the absorption of calcium in the baby's body, helping the baby grow and gain weight.

5. Regular feeding

Many parents will arrange to feed their babies every few hours, which makes the babies prone to excessive hunger and not being full. It is recommended that parents feed their newborn babies on demand, and feed them immediately when the baby shows sucking signs. This way the baby can eat enough and gain weight.

6. Timely prevention and treatment of diseases

You will find that babies who are often sick and suffer from illnesses will be underweight, while those babies who are less sick and well cared for by their parents will gain weight faster. Therefore, parents should promptly prevent and treat the following common diseases in newborn babies: jaundice, fever, pneumonia, eczema, omphalitis, etc., so that babies are less tortured by illnesses, eat a balanced diet, and gain weight naturally.

7. Avoid your baby from crying

If the baby cries frequently, it will affect the baby's drinking of milk. Once parents find that the baby is crying, they should find out the reason in time and meet the baby's needs. If the crying does not stop and the reason is unknown, you can pick up the baby, sing nursery rhymes to the baby, touch the baby, and soothe the baby's emotions.

8. Give your baby a good sleep

Newborn babies need to sleep at least 18 hours a day. Only when the baby gets enough sleep can its growth hormone be secreted normally. Therefore, parents should provide the baby with a quiet and comfortable sleeping environment so that the baby can sleep peacefully.

9. Wash and bathe frequently

Newborn babies are particularly sensitive to symptoms such as dirty urine and feces, excessive sweating, and eye mucus in the corners of the eyes. Parents should clean them in time to ensure that the baby is clean and comfortable, which is also helpful for the baby's normal weight gain.

10. Change diapers in time

Generally, a breastfed newborn baby will defecate 6 times and urinate 8-10 times a day. Therefore, if parents find that the baby's diaper is dirty, they should change it in time and not let the baby cry or be irritable, which will affect the baby's weight gain.

How to measure the weight of a one-month-old baby

Method 1: Wrap the baby in a towel and weigh him

Wrap the newborn with a soft towel, weigh it, and then subtract the weight of the towel and the newborn's clothes (including diapers) to get the newborn's weight.

Method 2: Parents weigh the baby while holding him

Parents weigh their newborns while holding them, and the result is the newborn's weight, minus the adult's weight and the weight of the newborn's clothes (including diapers).

remind

It is recommended to measure the weight of babies under 1 year old once a month. Each time you measure the weight, you should first let the baby fast and empty his/her bowels and bladder, otherwise the baby's net weight will easily deviate.

Reference standard for weight gain of babies within one year old

1. The normal full-term baby weighs about 2500-3999 grams at birth.

2. In the first three months, the baby's weight gain is 180-200 grams per week.

3. At 4 to 6 months, the baby should gain 150 to 180 grams per week.

4. From 6 to 9 months, the baby gains 90 to 120 grams per week.

5. At 9-12 months, the baby gains 60-90 grams per week.

6. Calculated by weight gain multiples, the baby's weight at 6 months is twice that at birth, about 3 times at 1 year old, about 4 times at 2 years old, and about 4.6 times at 3 years old.

Note: The formula for calculating baby's weight at different stages: weight within 6 months = birth weight + age in months × 600 grams; weight between 7-12 months = birth weight + age in months × 500 grams; weight between 2-7 years = age × 2 + 8000 grams.
