Joey went to his doctor today for 2 week check-up. He weighed 6 lbs 7.2 oz. He gained 13.2 oz in one week! I was hoping he'd be 6 lbs but he's nearly 6.5 lbs which makes me very happy. So my milk is working. He's eating enough and growing. We can see a difference. We are starting to dress him in some newborn size clothes (outgrowing the preemie sizes) and he is looking bigger.
