Hi Jazzy and welcome.
Yes, your dog Bubbles absolutely does count as a child. My little kitty is my daughter...as I impatiently wait to get a grandchild one of these days (drumming fingers on my desk).

Dogs and cats make fabulous children.
I also agree that aiming for a size rather than a number sounds like a very healthy perspective. You can go quite nuts obsessing about a number and variations can send you into negative spiral mode. I like the idea of just aiming for a size.
I've found this board to be extremely motivating and helpful. Hope you do too.
