['When my younger sister got pregnant, all I could think about was her as little baby.  It was a trip.', 'Did you get a little baby crazy?', 'haha not at that point!  a little, after I met my niece']
My sister is actually pregnant right now but, I'm not supposed to know about that yet.
When my little sister got pregnant, all I could think about was out childhood.  I remembered her as a little baby, and it seemed crazy she was going to have one of her own.
