At Connor's 4 month pediatrician appointment, his stats were:
15 lb. 14 oz. (55th percentile)
26.0" tall (80th percentile)
16.1" head circumference (45th percentile)
For the most part, Connor's routine hasn't changed in the past month. He eats 5 oz every 3 hours, poops once every 5 days, sleeps 5 hours continuously at night, and naps 3 to 4 times per day.
He is smiling and laughing more, and he's more aware of his surroundings. This increased awareness is often a bad thing because now he cries whenever we're out of sight.
