By the 15th week of your pregnancy, the hearing capabilities of your baby will develop. Read on to learn more about the crucial developments that shall take place in the 15th week of pregnancy.
Let the music play and be careful what you say as your baby could be listening.
Well she might not really understand what you say but her hearing capacity is in the process of developing. The three tiny bones in her middle ear have begun to harden but the auditory centres in her brain have not developed as yet so she might not be able to make any sense of the sounds. Also the amniotic fluid that she is in acts as a sound conductor, and so she will begin to hear the sound of your voice and your heartbeat.
Effects of Sound on the Foetus
Do not stay hungry and be careful what you eat, as she will be able to hear your stomach rumbling too. It would be a good idea to hear soft, soothing music from this stage on as she may be able to pick on certain sounds from outside the womb. You could even sing to her. There have been cases of babies who, soon after birth can recognize a certain song, which was sung to them while still in the womb. It always helps to have a familiar voice or song that generally soothes your child whenever she is cranky or upset.
Some Other Development this Week
Your baby requires all the help that she can get in terms of nutrition and rest as all her energy is directed at growing bigger and stronger. This week she will have developed eyelashes as well as eyebrows and the hair on her head will have grown thicker. By now she should measure about five and a quarter inches or 13.5cm. and she probably weighs about three and a half ounces or 100g. Isn't she growing quickly?
With time you are getting more used to the idea of your baby growing and developing inside you. As you both live together for long, you might feel the urge of communicating with her as well. You may also encourage your partner to participate in bonding with your new one. With the beginning of the second trimester, your baby is not only capable of hearing sound but also more aware of the environment around her.
Development of Organs
Cells inside your baby’s head are developing very fast and that are forming into unique tissues. These shall form her nose, ears, face and brain. You may still not find her ears in the ultrasound scans, but the maze of tubes shall make for her inner ears that shall connect with the tissues in her brain. Small indents develop by the 9th week by the side of her neck. However, they shall take a little more time to set in the actual location. They shall move up and get curled up to form the ear buttons that you shall be able to see when she is born.
Development of Ears
Her ears shall develop further all through the second trimesters. By the next few weeks her ears shall develop more sophistically. By the 24th week you can expect her to turn her head towards the source of sound.
How Does it Sound Inside?
Sounds travel through the open spaces the best. For example, you hear things much better in an open field than under the water. Since your baby is still growing and developing inside, she is not yet exposed to the open. She has amniotic fluid surrounded all around her. You also need to take into account the layers of your body that acts like a wall between your baby and the outside world. So, even if she has fully developed her ears, the sounds get muffled inside the uterus.
You and your partner can place your hands on your mouth and converse louder than usual sometimes for fun. This shall ensure your little one hear most of the pitches and sounds. Even though she may not understand the words, she is actually familiarising with her mommy and daddy’s voice. You may also try singing songs in the same way some time. These are some of the bonding techniques that shall let your little one know she is in a known environment when born.
Familiarising Baby with Your Voice
Once she is born, one of the most familiar voices to her shall be yours. Even though all sounds get transmitted through your uterus, your voice is amplified by the reverberation through different parts of your body, including the bones. According to research findings, your baby's heart rate shall increase upon hearing your voice. So, do ensure to sing, read story books aloud while she is still there inside you.
However, there is no need for the dads to feel left alone, as your baby shall recognise your voice too. You shall find your baby reacting in a different way to sounds and words familiar to her.
So, keep singing and talking to your little one. It shall surely be a wonderful feeling that you would love to experience time and again.
