I meant that you could have the queen start giving birth as soon as possible but the kits wouldn't count as born until the third day. Then you would change everyone's age to be identical to the youngest, otherwise they'd become apprentices at different moons. If a kit died before the day of birht they could be considered stillborn. Also if a nicheling has been bred at least once then console pregnancies will take the genes from the father so you could potentially not have the father close to the mother every single second (not sure if it sticks with the first breeding)
