Another from my mother. She told me to be sure I talk to my (unborn) baby so that it recognises my voice. The brain hurty part was the example she gave me about my nephew. According to my mother, when nephew was born he responded to his Dad's voice by turning his head when he talked, but not to his mummy's voice. According to my mother this is because my BIL said "Goodbye baby!" everyday to my sister's belly before he left for work.
So basically she's saying that the one, tiny sentence per day made him more recognisable to the baby than the voice of the person he literally lived inside of 24/7 for several months?
I just can't comprehend how that would make sense to anybody. I guess you could argue proximity, e.g. the mother's voice is further away whereas the Dad was leaning in closer... but nope, I still can't see any way that makes sense. What about when sis raised her voice? Or was lying down so that he belly was nearer to her face? It just makes no sense. Either way, I'm fairly certain my baby will know my voice as well as any other - I'm quite the talker. Even when I'm home alone I'm talking to my kitties constantly! I'm sure he'll hear something.
