If she didn’t want to have a baby so soon in a relationship maybe she shouldn’t have been sleeping with her boyfriend so early in the relationship.

BTW how is Sophie’s son Sonny doing? The last I heard he was living with the after effects of a bout of meningitis or something.

I think you meant “Sonny is the first child for both her and Richard.” The grammar works like this: If you were to take out the reference to Richard, you would say, “Sonny is the first child for her” – not she. When you add on another person, the sentence still has to work when you leave them out.
