Baby's weight

How much are your one month olds now? Or how much were they at one month? My little one was 7 lbs 8 oz at birth and now at 5 weeks he's 8 lbs 9 oz. I was told that he was in the 8th percentile for weight and 15th for height. Hes currently 21in which he was born 20.5. So basically I was told he's below average
