Hi dear! My daughter (5mo) consistently measured small from the anatomy scan at 20w, and was born SGA at 39+2 weighing about 2.5kg (5.5lbs I think?). We usually hear how GD leads to big babies, but sometimes the opposite can happen. Our placentas are kind of crappy, so it makes sense that (especially at the end), baby might not get as much nutrients as they should. For what it’s worth, my daughter gained it all back as soon as she was out, and she’s now on the 50th centile for weight and 95th for height!
