Experts say that your baby receives a certain amount of sensory information in the uterus to which they’ll respond, and can memorise, to a degree.

Towards the end of the second trimester, your baby starts to hear. While their soundtrack is your heartbeat, breathing, voice, pumping of blood and gurgles of digestion, they can also hear muffled noises from outside your body. While a daily dose of Mozart during pregnancy won’t make your baby a musical prodigy, he may recognise and be soothed by it when they hears it again as a newborn.
When you play music to your baby in the uterus, their heart rate will increase and they will move more. Shortly after birth, they may respond to music that has been played regularly, by becoming more wriggly and alert.

In the same way, your baby might also demonstrate that they recall and are comforted by other noises heard while in the uterus. These could be the theme tune of your favourite TV programme , or a story frequently read out loud to them. They  may also prefer your voice, paying attention when you speak.
One study found that if music was played while pregnant mothers relaxed, the same music would soothe their newborns when they heard it again. They ceased to cry, opened their eyes, and made fewer jerky (known as clonic) movements.

It’s not only the sounds heard while in the uterus that are thought to be remembered by your newborn. It’s believed they remember tastes too, as your Pregnancy diet flavours your amniotic fluid.
Some experts believe that this familiarity with flavours can help to establish breastfeeding, as your diet also flavours your breast milk. Your baby may even prefer these familiar-tasting foods during weaning .
One study showed that babies of mothers who drank a lot of carrot juice, during the last trimester, preferred carrot-flavoured cereal rather than plain. It highlights the important of a varied diet while you are pregnant, as it may influence your baby’s food preference.
