I dont't think there is any MUST to do.I guess its all up to you to decide what you wanna do with your child and how your child can adapt to it.
For example some kids can sit still to do craft at that age others just wanna run around and make a mess.
However at her age, it would be good to let her practice her walking, let her explore with her sense as you explain the items...dont't go to in depth just briefly like get her to touch smth rough and say :"rough! the cloth is rough"
Get the touch and feel books
Also you can have sing a long sessions with her good way to teach her hand signs and words.
I think she is too young to be potty trained....
You can let her feed herself with buiscuits though and mayb give her little like really little bit of water and spoon to let her feed herself..(probably will make a mess though)
dont't needa rush things enjoy every stage
Give her lots of encouragement for good behaviour and stern warnings for wrong doings.
