So I'm 29 weeks 3 days and I went for s sono to measure the baby because I have placenta lakes. Baby measured 3 lbs and a few ounces and she said he's just about in the 50th percentile. He's not big tho as we originally assumed he would be. And so I just hope even with the placenta lakes that he continues to grow nice and strong! Ps does the 50th percentile mean that he is average?
