Wizards in the Muggle World Challenge

I have decided to do two of each gender. For my girls, their baby Daddies don't have to move into the household? (Unless they decided to marry.) For my guys can I move more than one female in at the same time and the females can be pregnant at (around) the same time? Also, my Fishing Sim can this person also collect the collectibles? If my sim gets a skill from observing a friend can they then use that skill to get money from that skill? So say my Gardner Sim learns the fishing skill from Fishing Sim can he/she now earn money by both gardening and fishing?
