What would be a good way to tell someone their baby is ugly?

That might not be the best way to put it.  A better way to phrase it could be, "It's not what I expected." That's because expecting parents can have many different ideas about what their baby will look like and the reality may not always match up. Instead of focusing on the physical appearance, focus on things that are unique and special about their child - qualities like a laugh, or how smart they are.

An honest but gentle way to tell someone their baby is ugly is to explain that while the baby is still learning to form features, its face may not be as attractive as other babies. Gently point out some of the baby's distinct characteristics that make it unique and explain that those features may become more pleasing with age. Reassure the parents that every baby is beautiful in its own way and remind them not to harshly judge their child based on appearance alone.
