In fact this is not yet scientifically proven, and there are pro and cons arguments. Some studies, such the book I just read “Do chocolate lovers have sweeter babies: The surprising science of pregnancy”, indicate that fetuses can hear, react to music and even further they influence their development. Although no studies and/or book defined the idea that playing the music to your baby in the womb makes them smarter, some studies I have read support the idea that based on what kind of music you play and/or your baby in your womb reacts to –it depends his personality type.
I personally can’t really tell for my baby, as he is very active baby and as such he kicks almost all the time I assume he is awake, so I can’t make any difference. Yet my taste for music during this pregnancy is totally different from my first pregnancy. When I was pregnant with my babygirl 4 years ago – I was more into relaxing music: Mozart, Love songs, and similar, whereas now I’m fully into energetic music, it doesn’t matter if its R&B, Pop or Rock – it just has to be energetic. I don’t know if this effects their personality, and since there are always people arguing pro and cons I can’t say for sure. Neither can I say anything based on my babygirl as she contrary to the music I loved to listen during my pregnancy if very stubborn, not so emotionally expressive, but surely it is very smart. I don’t know how my angel will be, but one thing is for sure his astrological sign will be similar to his sister (which means his personality might be similar to her), as my due-date is exactly the same with my babygirl’s. One thing is for sure – as long as the music I love listening to makes me feel happy, powerful, and it makes me dance around and have fun – I’ll keep listening to it.
