4 month check up

So on August 16th, we took Caleb to the doctor for his check-up.  He didn't grow as much as I thought, but I'm okay with that.  He is 18 pounds 4 ounces and 25 1/2 inches long.  He is in the 95th percentile for both weight and height.  The doctor said his weight is about that of an average 7 month old.  I guess it shouldn't surprise me when people assume he's 6 or 7 months old.  He had some more immunizations, but the highlight of the visit was getting information about starting Caleb on solids.  I am excited to have him eat "real" food, but at the same time I don't like the fact that my baby us growing up so fast.
