Recently the brain U/S done indicated Lateral ventricles size of 14mm of either left and right Lateral ventricles.
What should be the normal size spectrum of Lateral ventricles for her age?
Have you talked with your doctor about your concerns?
Variations in ventricular size before and shortly after birth are associated with temperamental difficulties. Some of the morphologic differences between children with and without psychiatric disorders may develop very early in life.
Everything you want to find out about this you should ask your doctor because every child is different so the dimensions are different as well.
It has been a while since you have post this question so maybe now you have resolve all your concerns and problems and that your twins are fine.
