My DD is quite clingy but she has warmed up to Df now. For awhile she wasn't happy with him but we just made sure he did things with her, such as he feeds her her dinner, he reads her her bedtime story and tucks her into bed.
Maybe to begin with find something and start off with you and your hubby doing it with Bonnie then as time goes on slowly remove yourself so that it becomes something special your Dh can do with Bonnie.
