I agree. Parenting SHOULD count for more. But I would add that while the kids are being parented they could also gain experience somehow that relates to a future profession. The children have a preferred profession that the user can't change like you can with the adults. Then the child reaches 14 years with some direction in life. Then if the user needs to make a builder become a researcher or a farmer become a healer that's when you can do it, but not before. The child gains experience in something AND the mother could gain experience in that same skill. Since she is probably doing the teaching! So having children would have more of a positive increase for the mother.
