I took Luke in for his four month check up today. He's the size of a six month old. I don't need to worry that he's not eating enough I guess. We have been really worried about the shape of his head. It's really flat on the rear right side which was making it all misshapen every where else. We thought for sure he would need a correctional helmet. Well the good news ( I guess) is that the doctor was not all concerned and said it will round out when he's five months to two years old. I hope that's true and I always wonder if we should get a second opinion. I hate things like this when I never know what to do. We'll see how things go over the next few months. Hopefully when he starts to get more mobile, it will round out. Luke was 15 pounds and 26 inches long. He's a big kid and he's so darn cute.
