Is there a way to force twins or triplets?
Buying the fertility treatment lifetime happiness reward goes a long way toward encouraging multiple births (and the chance is greater if both parents have the fertility treatment instead of just one), but you can also influence the chance of twins or triplets by listening to the kids’ station on the radio and/or watching the kids’ channel on TV. There is no special boost to doing them both at the same time, but if you watch/listen to a lot, then you can increase your chance of twins and triplets up to 50% for twins and up to 10% for triplets (from the default of 5% and 1%).
