Weight concern

My boy has just turned 11 months. He is crawling around super fast and is almost close to walking unaided. I had him weighed today, and he has dropped a little from his line that he was following.. He is 9.98kg/22lb and 1 oz. He wears 9 to 12 month clothing - some are a little big on him though. Probably a silly question, but I'm assuming it is normal for them to drop a little weight once more mobile, or should I be concerned? He eats 3 good-sized homecooked meals & 3 bottles of 6oz, 7oz, and 8oz. It was at a self weigh clinic so nobody to ask for advice. Thank you 😊
