Choroid Plexus Cysts Found During Ultrasound

Today I had an ultrasound to see how little Eli is doing in there and he has two choroid plexus cysts in his brain which is a characteristic of Down syndrome but my doctor said that when babies have Down syndrome you can tell that they also have a heart defect and our sons heart sounded and looked perfectly fine so she said don't stress ourselves out looking on the Internet and freaking out. 9/10 babies have the cysts and by the time they hit the third trimester the cysts are gone. I'm not scared but of course as a first time mom I am a little worried. I know he'll be fine though. I just ask that everyone keeps my little baby in their prayers.
