My almost 9 month old is 23lbs!!!! She weighs more than the average 1 year old. Is this something I should be concerned about?!

She’s always been in the higher percentile for weight and height at all her appointments and her pedi hasn’t ever really said anything.... she goes to the doctor soon for her 9 month appointment but at her last appointment (mid March) she was just under 19lbs... and now she’s gained 5lbs in around 2 months! She crawls and is standing. She was almost 9lbs at birth.
