Paid pregnancy leave? Disability?

Barbie • So happy to be a mother of 2 beautiful lil girls..and 1 more on the way. #PowerPuffGirls

Okay so Im just confused. I just went on Maternity Leave this past Friday. My job says it will pay 90% up until a certain point and then 50% afterwards. I requested bonding time also after post Partum. In my last job with the school district I ended up getting DISABILITY somehow. Does anyone know how this works? Am I supposed to fill out Disability Insurance at some point? Any comments are welcome.
