Low percentile in length

Hi all! My baby boy turned two months this past week. He has been a smaller baby since birth. Both his weight and head size went from <3%tile to 15% at month 2. However, his length is still at 5%. A bit growth but not a lot on the percentile. His dad and myself are not the tallest so we are not expecting a tall baby. Just wondering if there are ways to help him catch up on his length ( things we can do now or in later months) Im super anxious 🤧
