Babies gain about an ounce a day on average during this period, or half a pound per week, and they should be back to their birthweight by their second-week visit.
Expect a growth surge around 3 weeks and then another one at 6 weeks. A baby should gain about half a pound every two weeks. By 6 months, she should have doubled her birthweight. A child is still gaining about a pound a month.
If you're nursing, your baby may not gain quite this much, or he may dip slightly from one percentile to another on the growth chart.
Even so, by the time he reaches his first birthday, expect him to have grown 10 inches in length and tripled his birthweight and his head to have grown by about 4 inches.

Between the ages of 1 and 5 your child will usually gain about 10 pounds, five pounds between ages 1 and 2 and the remaining five pounds between ages 2 and 5.
The average 2-year-old weighs between 22 to 33 pounds. The average 4-year-old weighs between 28 and 44 pounds. You might notice your preschooler has less of an appetite or becomes a picky eater.
These are normal phases, and a decreased appetite can be a sign of slower growth. Continue offering healthy foods for meals and snacks, and don't be concerned if your preschooler refuses to eat at times or can't seem to get full at others. Most health care providers will use either a BMI chart or growth chart to measure your child's weight.
