No,
The first part is mandatory, the second optional.
The Rules for Family growth (page 5) state:
Players must have room for offspring in their home before they can use this action – that is, they must have more rooms in their home than they have Family members. After taking Family growth, the player may choose to purchase a Minor Improvement
Note that in general, a player must be able to use an action to be allowed to place a worker on it. (page 3),
A Family member may never occupy an Action space without performing its action.
Therefore you cannot place a worker there just to block another player.
