A vaginal sound system has been made for pregnant women
If you are a massive music fan, you will probably want to brainwash your child with your taste at the earliest possible opportunity.
Well, now you can play them Tame Impala before they have even left the womb.
New technology allows mums-to-be to insert a speaker into their vagina to give their unborn child its own personal sound system.
It is called the Babypod vaginal speaker and was designed in Spain.
The device attaches to an MP3 player and while there are lots of speaker systems to put around your abdomen already on the market, this is the first that is inserted internally.
The developers say there is no risk to the baby as batteries and bluetooth are not needed.
The volume is also limited to 54 decibels, which is about the same level as a washing machine.
There are various theories about whether unborn babies respond to music.
But the people behind the Babypod carried out tests which they say prove that foetuses do indeed respond.
"Babies learn to speak in response to sound stimuli, especially melodic sound," the firm says.
"Babypod is a device that stimulates before birth through music. With Babypod, babies learn to vocalise from the womb."
Apparently, you can also leave your unborn child a voice message.
It's all a bit odd and it gets stranger still as just before Christmas, Babypod put on the first ever concert for unborn babies.
Ten mothers-to-be sat in a concert hall, while a singer called Soraya Arnelas, who came 23rd in the 2009 Eurovision contest, sang Christmas carols.
The women, apart from Soraya, all wore Babypods while sonograms captured the unborn babies' expressions on a big screen. At some points the images appeared to show their mouths moving in time with the music.
If that means they are learning the words, probably best to stick to Let It Go rather than blasting Kanye West's All Day in there.
While the foetus may well respond, there is nothing to really prove how beneficial it can be to a baby's development.
And at £110 it's an expensive way of forcing your unborn baby to love Adele.
