During her first year, Baby grows up and grows very quickly. If at one year, he has almost tripled his birth weight, it is during the first three months that his transformation is the most important. Parents take stock of the development of Baby, month by month.
Baby weight from birth to one year
Babies grow and grow very fast. “During the first three months of life, the growth of the child explodes,” says Dr. Henri Bouchet, a pediatrician. It takes between 800 g and 1 kg per month. Side size, it takes between 3 and 4 cm per month.
Between 3 and 6 months, the growth curve slows down and weight gain decreases. The child takes 500 to 600 g and 1 cm per month.
“From 6 months, until the age of one, weight gain continues to decline.” These figures are of course indicative. And as the pediatrician explains, “a child who does not take or gain little weight every month is not necessarily sick. Every baby is different and growing at their own pace. It’s very variable. Genetic factors are also involved. The key is to take into account the body mass index (BMI), which calculates the rate of overweight. Moreover, as soon as the child begins to walk, around 12 months, the BMI decreases. The latter slows down during the child’s second year and stabilizes during his 3 years. As Dr. Henri Bouchet also says, contrary to what one might think, “weight gain is not really different between breastfed and bottle-fed children.” Moreover, “before the age of 9, the growth curve of girls and boys is almost similar. ”
Baby weight at birth
At birth, the infant weighs, on average, between 2.8 and 3.2 kg. However, for various reasons (genetic, complications during pregnancy …), the weight of the child may be more or less important.
Up to 4-5 months, your baby feeds exclusively on breast milk or infant formula. If you are breastfeeding, your newborn baby needs between 8 and 12 times a day. If you have chosen a bottle, your child takes on average, daily, six bottles of 90 to 120 ml each.
Baby weight at 1 month
At 1 month, your baby weighs between 3.4 and 4.4 kg. But according to the birth weight, these figures can vary greatly, the average low being at 3 kg and the average high at 5.6 kg.
Even if your appetite starts to regulate, your baby always drinks 6 bottles a day of infant formula. If you give breast, it often claims and you breastfeed on demand. Until the age of 3 months, the digestion of your child can be difficult and punctuated with crying. Do not hesitate to make an appointment with your pediatrician to know the exact reasons for these inconveniences.
Baby weight at 2 months
At 2 months, your baby can, according to his corpulence, weigh between 3.4 and 6.4 kg. Nevertheless, the average weight is between 4.4 and 5.2 kg.
Your child’s appetite continues to regulate: he drinks between 5 and 6 bottles a day. For lactating moms, your toddler still claims very often.
Baby weight at 3 months
At 3 months, the smallest babies weigh about 4 kg and the strongest, 7 kg. The average weight is between 4.6 and 6 kg.
On the feeding side, the number of feedings decreases: your child takes 4/5 feedings or bottles per day. Note that in general, at this point, the digestive problems of your baby disappear. Regurgitations were treated normally by the pediatrician.
