First of all Welcome to YT.
Do you use a harness when you walk your Bailey? (safer for their tracheas)
I have a Bailey also, 5lbs almost 20 mo
Have you ever done formal training clases with her? They do teach you to walk your dog without them tripping you. When you have her on a harness and leash, keep the leash in the hand on the side you want her to walk on and don't have too much play in the leash. Praise her (give treat if want) and as she catches on give her more play in the leash.
My dog caught on fast, and doesn't crisscross in front of us anymore. We were afraid of stepping on her
Good luck
