Weight of preterm baby at 1 year
My baby was 6 weeks preterm and weighed 5 1/2 pounds at birth. She is now 5 1/2 months old and weighs about 16 pounds. What should her weight be at one year if she`s already tripled her weight? She is a good eater and very healthy thus far.
Typically an infant doubles their birth weight at 4 to 6 months of age, and triples it by one year. However, it will be different for a preterm infant, with many variables. There are many factors to look at as your child grows; with their weight being just one area when looking at their overall growth. The person who is most familiar with your infant is the one who can give you the best information regarding growth and estimating their weight at a year of age. That person is your child’s health care provider.
