What is a good percentile for baby weight?
A baby on the 50th percentile for weight, for example, is right in the middle of the normal range: 50% of babies their age are lighter, and 50% are heavier. A baby on the 5th percentile weighs less than 95% of other babies of that age. A baby on the 90th percentile weights more than 90% of other babies that age.
Why do babies drop percentiles?

Is a higher or lower percentile better?
Percentile ranks are often expressed as a number between 1 and 99, with 50 being the average. So if a student scored a percentile rank of 87, it would mean that they performed better than 87 percent of the other students in his norm group.
What does 2nd percentile mean for babies?
Infants and children with a length-for-age that is less than the 2nd percentile are classified as having short stature. Infants and children with a weight-for-length that is higher than the 98th percentile are classified as high weight-for-length.
Is 5th percentile good or bad?

What does 99 percentile mean for babies?
“If you line up 100 babies of Arlo’s age, from the shortest to the longest. Arlo would be 97,” says Dr Joe Hagan from the American Academy of Pediatrics, explaining what it means to be in the 97th percentile. “If you count head circumference he’d be 99.”
Do small for gestational age babies catch up?
Most babies born too small for their gestational age catch up over the first two or three years of life. However, in about a third, complete catch-up growth does not occur. These children remain small and don’t reach their genetic potential as defined by their parental heights.
