First Time Mom

I'm a first time mom and already so confused on what to do. I have a few questions i don't know if there's a certain age or if you just learn as you go.

- When do you start to give them a sippy cup?

- When do you teach them their colors/how to write and draw?

- When do you potty train them?

- When do you start to give them baby food?

- When do you start tummy time?
