20 week ultrasound

We had the 20 week ultrasound last Tuesday. The baby was so active that we only got one picture. We are having a boy. We found out today that the baby's kidneys are a little enlarged. We get to have another ultrasound at 30 weeks to check on the kidneys. Dr Beckett is hopeful that the kidneys will fix themselves by the next ultrasound. He said that there is probably a blockage so the urine can't exit the kidneys like it should.
