When to start potty training

Chloe

I have a 16 month old girl and I'm just not sure when to start. Another mom at work has a 13 month old who is already learning. My daughter is bilingual and prefers Spanish (which is inconvenient since I don't know it) I know bilingual babies tend to develop slower because they process both languages at once. I'm just wondering when a good time to start would be and how to do that with her. Any tips are very much appreciated.
