Follow up anatomy scan.

So on Tues my husband and I had a follow up anatomy scan. Our baby boy was breech at the first so there were some areas they could not see. This one he's finally head down and ready to go. At the first appointment his kindneys were slightly englarged. At our scan Tues they were still the same but still larger than my ob would like. So now she is referring us to a fetal medicine specialist to get a closer look. They both didn't seem too concerned and just want to be sure. But being a first time momma, news like that is just hard to hear, regardless of the severity.
