Welcome! My girls sleep in the bed with me. You don't have to stop it. There was only one night when I half-woke and was half-annoyed wondering what this thing in the be was but before I could brush it away, I remembered that IT WAS THE BABY!!!!!
But you probably already know that since you have Minnie Mouse besides the babies. I can't see the picture, but "Chihuahua" seems to heading in the same semantic direction as "Pit Bull"; both of my Chis are crosses and they're very different from each other, but the curly tails, shivering, and sensitive personality seem to be dominant characteristics.
