Today we had our growth sono for my 2 vessel cord. Now with the GD they do growth sonos too. The tech told me to 'be careful' after the sono and that babies put on all their weight now so I should watch myself. I know she isn't a doc or a nurse, but our baby was only in the 52% tile at 2 pounds 8 oz at 28 weeks. Is 52 considered high for GD? or is she just giving a general warning?
