How many babies?

Actually zero right now because I'm in a new save, but I plan on having them have six after I've played them for all 4 seasons (long life, one week per season). First I want them to have some adventures, get some skills mastered & make some money, then I want them to move to the house I have picked out for them in Windenburg. I want six, because I have plans for each one after they've grown up, involving some of the more recent packs.
