Our little guy is already 6 weeks old. He is such a joy. He's really starting to smile more as he interacts with us. We started letting him try to sleep through the night a few nights ago. The first night he slept from 11pm-6:15am, the second night 11pm-4:30am, and last night he slept from 11pm-7am. He's doing great! He's a sweetie!
