Electronic Babies

All the teenage girls in our neighbourhood have been given electronic babies to persuade them that it's not a good option to be a single teenage mum.
Unfortunately, the school has programmed the babies to wake and cry at identical moments, and the girls think this is very amusing. They also pick up and channel that rhythm from mobile phones that is so irritating when it interrupts music on the radio or over speakers, so as the girls text each other to complain about the constant crying, another SFX is added to the cacophony.
There are groups of girls wandering round town with big plastic babies in babyslings; does this make their mums electronic grandmas?
I remember when Justin and Colin, those well-known gay interior designers ('now it's time to dress the room') adopted an electronic baby. They fell in love with it and cried when they had to give it back. I thought that was very touching.
