My daughter was born on 06/20/19. She weighed 7lbs 1/2 oz at birth. That Monday 06/24 we went for a newborn check up and she weighed 6lbs 08oz which is normal for them to lose a little weight at birth. We went today for a weight check and she weighs 6lbs 12.5 oz. The doctor seemed a little concerned and wants to see her in a week again to see if she’s gained any weight. Has anyone has this issue? My son didn’t have any issues gaining weight so this has me concerned and stressed.
