toddler or puppy???

i promise some days i do not know whether i have a 2 year old or a puppy. Livi pees everywhere! (i'm sure she will hate me for this when she is 16). Her diapers no longer hold her pee. She often takes her diapers off and runs from me then pees on the floor or under the table. She then thinks its funny and splashes around in it. Not more than 3 months ago we were doing well with potty training, she was excited about going to the big girl potty and she was starting to tell me when she had to go. But things have gone in reverse, now she does not want to even try to go to the potty and instead will run from me when i try to change a wet or dirty diaper! In addition to her pee issue, she now has entered a licking phase. If we are just sitting on the couch, if she is feeling feisty, she will climb on you and lick you. Arms, face, chest, whatever skin is exposed. We have tried to get her to stop, but she thinks its hilarious! Am i dealing with a toddler or a puppy?
