15 month check up!

My son had his 15 month checkup today. He will 16 months March 16th. He is overall healthy. He is 22lbs and 30 inches tall. Is anyone else's baby around that size? His doctor said he is 50th percentile for weight and 20th for height. His dad is kinda tall and I'm average sized so I'm surprised at the height part. He got 3 shots and didn't cry at all he is definitely great with getting shots/ finger pricks. He isn't fazed by them I'm so proud of him. He has done great all day since. He was a little sleepy after the appointment and took a nap but no fussiness and is happy as ever!
