Where can I find a basic list of english phrases one might use with a toddler?

My colleague works with preschool kids with hearing impairment here in Hong Kong. Usually she speaks in Cantonese, but she gets the occasional English client. As her mother tongue is not English, she’s asked me if I know of any resources that might help her speak stuff like, “Will you pick up the ball for me?” and “Do you want to go to the toilet?”

For the most part her work is working on the children’s hearing impairment, but she figures that which she’s at it she might as well speak to the child in a more fluent manner/with rich vocab.

Any idea where she could go? I’ve googled “preschool English phrases” etc, but don’t seem to be able to find a simple list of things.

Also any books or other suggestions where she could improve her preschool English would be great. There’s a lot of resources for adult, business English, etc, but she just wants the most basic toddler phrases….
