Tinkerbell absolutely loves the water! She often falls asleep during a bath
For her first bath I remember filling up an old dishwashing tub enough to cover her up to the knees or so with warm water and just putting her in it and letting her play a bit, I used a cup to pour water over her body. My other yorkie Gizmo hates the water, especially the running water is very scary for him. I would suggest not putting the water on her head the first time and don't have the water running. I think some just like it and some don't, no matter what you do.
