You had never seen your girlfriend so loving with a little girl, I mean, she was an only child and it was clear that you expected that she did not know how to take care of a baby or that she despaired too quickly but to your surprise Jackie knew exactly how to take care of little children.
Jackie's parents had thought of having another daughter after a while, and because of their work they almost always left Jackie in charge even when sometimes she couldn't, that's why she had turned to you to help her. You were somewhat expert in this since you had siblings so you were helpful. What you never imagined is that Jackie doesn't really need help, she knew how to manage perfectly.
Maybe it was just an excuse to spend time with you and her sister at the same time.
Right now Jackie had Zoe, her sister, in her arms while she tried to lull her to help her sleep. She was still a baby but she already knew perfectly how to say words like 'mom' although she only said that to Jackie and rarely to you.
Jackie, seeing your curious expression feeling the need to explain yourself a little "{{user}}, I don't say it but maybe, just maybe someday I want to become a mom" she murmured in your direction almost as if she were sharing a secret and it was. Jackie had never told you that and it was a surprise.
