I am a grandmother not a new mom but I have had my premature born grandson around my jealous Ana Grey. I always talked to Ana Grey and explained about little Dino and that she needed to be good to him. You know Ana Grey has always been respectful of Little Dino from day one. She would sit quietly on the back of my rocking chair while I feed the baby his bottle or rocked him to sleep. And she would sit quietly on her perch while I changed his diaper. She seem to understand that the baby needed me more than her. After I put the baby to bed of course Ana Grey got oodles of scratches and loving. The same happened when I first got Sterling Gris, my CAG at 5 months and he needed a night feeding. Ana Grey never interfered and would sit quietly on the back of my chair or on my shoulder and patiently wait until Sterling was finished eating. Of course, now that he is older, she beats the tar out of him, but then that is what siblings do!!! The point is, greys are very smart and intuitive and if you talk to your grey and always include Charlie I believe all will be fine. From your post, you are all ready doing that.("...laying down with Charlie on my stomach. ....") Congratulations on the new addition to your family.
