A baby typically reaches 9kg around 6 to 9 months of age, though it varies by gender and individual growth, with baby boys often hitting this weight slightly earlier or being heavier, while girls might reach it closer to 9 months or just after, often around 9-10 months for the 50th percentile. For instance, a 9-month-old boy might average around 9.3kg, while a 9-month-old girl could be around 8.5kg, but 9kg falls within the normal range for both at this age and slightly before/after, notes the Cow & Gate baby club, Pampers, and Healthline.
The standard weight chart for children shows that a 1-year-old child's weight ranges from 8.9 to 10.4 kg. A 1-year-old boy's weight is from 8.9 kg to 10.4 kg while a 1-year-old girl weighs from 8.9 kg to 10.1 kg. Children under 6 months old gain weight between 125 grams and 600 grams per week.

Your baby may have some of these symptoms:
Other factors should be considered when a baby: Doesn't gain at least a half-ounce (15 g) a day by the fourth or fifth day after birth. Doesn't regain birth weight by 2 to 3 weeks after birth. Doesn't gain at least 1 pound (454 g) a month for the first 4 months (from lowest weight after birth vs.
Language and communication milestones at 2 years
The average weight for full-term babies (born between 37 and 41 weeks' gestation) is about 7 pounds (3.2 kg). In general, small babies and very large babies are more likely to have problems.
Common growth spurt ages
Infants typically grow 10 inches (25 centimeters) in length and triple their weight during their first year [1]! Growth tends to slow down in a child's second year and we won't expect the same rapid changes in height and weight to continue.
Soon after birth, an infant normally loses about 10% to 12% of their birth weight. By about age 2 weeks, an infant should start to gain weight and grow quickly. By age 4 to 6 months, an infant's weight should be double their birth weight. During the second half of the first year of life, growth is not as rapid.
Signs You're Having a Big Baby
ACOG says ultrasound is no better than a provider's exam in estimating fetal weight, suspected macrosomia should not be an indication for induction of labor, and planned C-sections shouldn't be performed unless the estimated fetal weight is 10 pounds or more in diabetic women or 11 pounds or more in other women.
The first three months with your baby often seem the hardest. Sleep-deprived parents can feel overwhelmed, but that is normal and you will quickly learn how to read your baby's cues and personality. Don't worry about “spoiling” your baby at this stage.
Babies start rolling over as early as 4 months old. They will rock from side to side, a motion that is the foundation for rolling over. They may also roll over from tummy to back. At 6 months old, babies will typically roll over in both directions.
