The method know as three dimensional ultrasound scanning is used in early pregnancy, it provides 3d pictures of the unborn baby. Most of the time these pictures are quickly collected and joined together and animated to created a 4d scan.
Three dimensional scanning works similarly to the usual ultrasound methods except that the ultrasound scanning pulses can be sent from multiple directions. The ultrasound pulses are reflected back and captured and provide information to construct a 3d picture in in a similar manner to 3d pictures. 3 dimesional ultasound scanning was started by stephen smith and olaf von ramm.
It is important to understand that sonologists everywhere always pictured three-dimensional images of the body in their minds while carrying out 2d scans. However, until recently it was very difficult to do this type of reconstruction on on information using ultasound scanning. The advent of baby scans for the first time allowed us a peek into the brain of a sonologist and hence letting us view the images on the ultrasound machine.
3d imaging should utilize ultrasound energy following the same limits as conventional 2d ultrasound to create the 3d images. There is no data to suggest any harm due to 3d ultrasound, its use in none essential situations should be undertaken with the understanding that a risk may exist.

There are three distinct stages of pregnancy, called trimesters, each about 13 weeks. The stage of pregnancy, or trimester, is important to your baby’s growth and might be uncomfortable for you. As your body adjusts to the raging hormones of a new pregnancy, you might experience morning sickness and moodiness. Your breasts will swell and you will miss your period. Your baby will grow from a small cluster of cells to an embryo with the beginnings of eyes, ears, fingers and toes. The baby will be able to move his arms and legs. At the end of the first trimester, you may notice that you are “showing” and your doctor may be able to tell you what sex the baby is.
During the second trimester, your belly will grow as the baby does, and you will begin to feel the baby move. You may experience headaches, dizziness and backaches from the changes happening to your body. Luckily, morning sickness has disappeared, but you may begin to retain water. Your baby’s bones are developing and he is covered with a fine layer of hair called lanugo. As your belly expands, you continue to gain weight. Despite this, the second trimester is the time most pregnant women enjoy the most.
The baby’s growth slows by the end of the third trimester. Vital organs are developed and fat begins to develop under the baby’s skin. During the last weeks of the third trimester, the baby begins to descend into the birth canal. You will have gained 25-35 pounds (ideally) and you may experience some fatigue and numbness in the pelvic area. Urination is more frequent and your breasts may start to feel heavy and leak. Of course, the third trimester ends with the birth of your baby!

Are you worried about your child’s reading habits? Perhaps you feel he or she should be starting to read, but they have no interest in books whatsoever? I had the same problem with my son. Gosh, he would rather chew on ‘The Big Book of Nursery Rhymes’ than read a word from it! Here’s a short list of questions which I find very relevant if you’re concerned about your kids’ reading habits.
Question: There are some scary children stories like “Hansel and Gretel” out there. Will they disturb my child?
Answer: The important thing here is the manner in which the story is told. If you’re reading to your child in words, then there should be no problem. If however, you’re watching a movie version of the story, then perhaps there is more impact on the child. However, this is not to say you cannot allow your children to watch, say, “Snow White and The Seven Dwarfs”.
Just make sure you’re there to explain if he or she has any questions - then they’ll be fine. As a side note, do remember that scary stories are also required for a child’s psychological development - so don’t shield them from such material totally.
Question: I’ve problems finding out which books are best for my child. Please help!
Answer: There are some very good childrens’ books out there. Some of my favorite classic childrens’ tales which I freely read to my kid include Winnie the Pooh stories, Aesop’s Fables and nursery rhymes of any sort. If you’re interested, check out the list below for more book references:
* Bernice E. Cullinan, Read to Me: Raising Kids Who Love to Read. Scholastic, 1992. * Kate Hall McMullan, How to Choose Good Books for Kids. Addison-Wesley, 1984. * Jane A. Williams, How to Stock a Home Library Inexpensively. Bluestocking Press, 1995.
Question: How can I motivate my child to read?
Answer: This has got to be THE most common question parents ask. Well, the answer is simple. Have FUN reading to your child and he or she will be motivated to read!
Vary the types of books you get for them. Some children prefer fairy tales, others prefer books about animals, trucks, or cartoons. Expose them to different genres of literature. If you find one area they’re really interested you can zoom in on it and focus on those type of books. You can also try visiting your local bookstore and let your child choose a book on his or her own.
Oh, here’s another tip - make your reading dramatic. Sure, it’s a bit weird initially, but it does wonders for motivating and stimulating your child. Use funny voices and dramatic gestures! Vary your volume level, act like a clown!
