My LO is short baby......

We had 9 months check up today , and my LO only 26.5 inch length (11%) , she born 3 weeks early but her length was 48% at birth and her weight always being the small side, since March she only added 2 inch in her length......Dr was happy cause she is growing but I kind of feeling it is a little too short for her length.....my LO is very active baby, she crawling everywhere and standing by her own for a while, can walking with out hold for 2-3 steps eat solid foods like champion but just an small baby😅 How is your LO growing???
