All babies are different, and they will not progress the same. Therefore, when you look at an infant weight chart you should consider it a suggestive weight. However, this type of information is a great way to see the overall average weight and size of a typical infant.
There are a few guidelines that you should keep in mind when tracking your baby’s weight, and comparing their progress with an infant weight chart.
- During the first six months, you should expect to see a growth of ½ to 1 inch (about 1.5 to 2.5 centimeters) each month. They will gain an average of 5 to 7 ounces (140 to 200 grams) each week. Most infant weight charts suggest that a baby will double their birth weight by the time they are 5 months.
- From six to twelve months, an infant will see a growth of 3/8 of an inch (about 1 centimeter) each month. Your baby will gain 3 to 5 ounces (85 to 140 grams) every week. Infant weight charts typically suggest that a baby will triple their weight by the time they are a year old.
Each time you go to their well baby checkup, the pediatrician will discuss and share your baby’s infant weight chart progress. In discussing your baby’s weight and measurements, they will address any concerns that may be seen in the development of your baby.
You always want to remember that every baby will have times where they are not actively growing. During these times, it is typical for your baby to not have a weight gain, and they may even experience a weight loss. Do not focus too much on your baby’s actual spot on the infant weight chart curve. You want to place your focus on the big picture, meaning, the overall growth.
