Havanese large or small

I have to address the issue of what is the the perfect size for a Havanese. I feel a family with children need a little larger dog, so they should be looking for a pup that is going to be around 14 lbs.
The children need a pet that take the rough play and and loving quite time. Usually the adults coming in to purchase the pup want a tiny one not thinking of which size would be best for their children.

So the question is the smaller pup or the larger pup.
