Zoe went for her 4 month appt. Weight: 14 lbs. 5 oz. 50th percentile Height: 25 inches 70th percentile Head: 41 cm 40th percentile. She also had to get 4 shots. I think this was her first official meltdown, she screamed and screamed, like I had never heard. She also needed a nap, so that contributed to the meltdown, but I felt so bad. Luckily, she fell asleep in the car on the way home.
