20w U/S- small head normal cerebellum

Kay • NJ mom of 2 👨‍👩‍👧‍👦

Just had our anatomy scan, our little boy looks great with the exception of a head measuring 1.5 weeks behind. (This was a level 2 with the perinatologist- high risk) he said his cerebellum is right on target, but his head is measuring slightly behind. He said he wouldn't be worried but we'll check in 6 weeks for a growth u/s to confirm. I know that should make me feel better but I'm still a little on edge. Anyone have any insight?
