Welcome! You must, with all your experience, feel right at home already on a forum like this.
I'm still a bit new--both to the forum and to yorkies, but my two and my mom's two (one yorkie, one shorkie) have really brought the life back into our family after several years of struggling with losses and other stress. I know your babies must mean the world to you. After being a caregiver for a family member, it feels good to provide care again for another living, loving creature. (I cared for my grandfather.)
We'd love to be pseudo-introduced to your furry family if you'd like to post some photos!
ETA: I'm very sorry about the loss of your mother.
