This latest gimmick from America (where else) plays your baby sounds like a mums heartbeat. Whilst they are still in the womb. Nothing wrong with that, what worries me is that the heartbeats get faster so your baby is hearing a sound like the mum is stressed/upset etc. Surely that can't be good for them? Research shows that fetuses prefer music with a slow beat. Also, the website is full of dubious claims, no real research and stuff that is plain wrong. American pregnant mums seem to have fallen for the whole thing and post positive reviews based on no evidence whatsoever. What do British mums think? Am I just an old fuddy duddy?! Or do unborn babies and guillable mums to be need warning about this c**p?!
