She might be smaller than 3 lbs. Hobbs was 1.8 lbs at 8 weeks. Now he is 1 week shy of 7 months old and he has not quite broken the 3 lbs mark yet. He is probably 3 lbs. immediately after meal time. I was really worried at first about him being so small, but he is a healthy little guy!!! He knows to get out of the way of people so he doesn't get stepped on or sat on. He is just very petite
