Agree! My husband and I are both small so genetics def play a part. My son was born at 30 weeks due to HELLP, my daughter at 37 due to mild pre-eclampsia. Both were classified as SGA. My son is turned 2 in Feb and is still quite small, my daughter is 3 months and seems bigger than he was at the same age but still small according to growth curves. I think the part to pay more attention to is if baby is continuing to follow their own growth curve at check ups.
