Why is the cerebellum measurement 3 weeks behind head circumference

[xxzoe85xx]

Hi, would anybody be able to share their percentile measurements at around 20 - 30 weeks for individual things?

I'm 22w4d and my scan percentiles just seem so spaced out. I know they are in 'normal' range, but I cant help think that id prefer if all were on the larger side or all on the smaller side, what I dont understand is the huge gap between cerebellum measurement vs head and abdomen circumference?

Head Circumference - 78.8%
Abdominal circumference - 86%
Femur length - 39%
Cerebellum - 30.8%

Did anybody else have such a gap between the measurements?

I had massive gaps with my measurements. You'll go back in two weeks and they'll tell you something else. I really wouldn't worry although I know it's hard. Each baby grows at its own rate.

Thankyou I hope so! Do you remember what your measurements were? X

The measurements will all have some error from how baby was lying etc so as long as they are in the normal range then things are fine.
