17 weeks is still pretty young to expect total potty training success (in my opinion). I will be curious to hear other member's ideas. Potty training takes a lot of consistency and it is definitely hard to do when you are gone during to the day for 9 hours.
How does Kash do with his potty training in the evening when you are home?
Potty training is so hard, but I'm sure Kash will pick up on it!
Good luck!
