Re: Is it smart to have families on the Enterprise-D?
As to the matter of children on starships TNG continued to do stories about children they weren't forgotten about, but they have to work around the shortened working schedules the minors are allowed.
And when children are on a set (even Wil), the production has to pay for a teacher as well. I don't remember the numbers, but child actors were required to have X hours of instruction each day they worked.
