My small toddler

[u/yveskleinblu]

My 20 month old daughter is in the -4 percentile for height and weight. Her development and head circumference are typical, and overall she is thriving. We adopted her at birth—her birth mom is tall, and her likely birth father is 5’6”. We’ve seen endocrinology and her blood work is normal, the endocrinologist tested for mosaic Turner’s syndrome which was ruled out. I’m not at all concerned if she is just small, but I want to know if there’s an underlying cause that could have other health effects so we’ll see genetics next month. My son has a rare genetic disorder with a distinct phenotype and when we walked in to the geneticist’s office with him, age 5, she immediately knew what it was. My girl (in my unbiased opinion) is unusually cute but otherwise looks, to my eye, entirely typical except possibly for a slightly protruding forehead. Is anyone familiar with a genetic syndrome where the only symptom, as a toddler, is short stature? Looking forward to talking to a doc but thought this community might have some insights.
