No Way! No How!
You cannot love them too much. And there is nothing wrong with them being your babies.
I have one skin kid and I feel like the love for my fur babies is very different for the love of my little girl. I was pretty young when I brought my sweet Emmie into this world, and since then have decided that 1 child is enough for me, and hubby. Copper and Maddie are going to be me babies for their whole lives. They complete that part of me that wants to continue to nurture and care for something. I don't feel like I could ever love them too much.
