    However, 3D and 4D scan offer you the image of your baby skin which is relatively prettier than just seeing her organs. With 3D and 4D scan, you can see the shape of your baby’s mouth and nose, and you’ll enjoy the pleasure of watching your baby yawn or stick her tongue out.
    3D and 4D scans are as safe as 2D scans because they feature sections 2D images converted into a picture. Doctors and midwives hardly recommend 3D and 4D scan because the level of exposure to ultrasound is beyond the safety limit. Ultrasound that exceeds 45 minutes or an hour is considered above recommended safety limits.

    For a new parent that is interested in a 3D or 4D scan, you’ll have to pay and arrange for it privately. The charges vary depending on the ultrasound clinic you are using. Some clinics also give a recording of the scan on DVD.
    The equipment required for 3D and 4D scan is exorbitant. They have limited chemical benefits, and doctors and midwives emphasize that this should only be done when it is medically necessary. Therefore, replacing normal 2D scans which are used for routine maternity care is highly unlikely.
    However, the optimum time for a 3D or 4D scan is between 26 and 36 weeks of pregnancy.
    Your baby has little fat under her skin before 26 weeks of pregnancy. So, this is the time when the bones in her face show through while after 30 weeks is a stage when your baby’s head goes deep down in your pelvis. So you will hardly see the bones of her face at this stage.

The same applies to pregnant women with a lot of tummies fat.

    Most of the time, a good sonographer asks pregnant women to go for a walk or to visit back in a week to have the baby moved to a better position. Even if the face view isn’t clear enough you will be able to see her fingers and toes instead.
