I have an appointment on Thursday as well as a growth ultrasound. I'm excited and anxious to see if she's put on any weight. Last two times we've been to the doctor she's only been at 2lb11oz. I know that ultrasounds can be off, but still, when the average baby is almost 4.5lbs at this point it's a bit worrying. She's doing great in length but she just needs to pack on some pounds!!
