Hi, a warm welcome to the site.
If you work in England the current framework is
EYFS 2014 which has three sections you can use to link theories to.
There is much research to this outcome as it looks at theories such as attachment and the range of ways that theorists consider children learn.
Has your tutor recommended a
handbook for your course and the theorists you need to be studying for this?
