What belongs in your text
Add two to four short points for each job. Explain your work, not only your title. For childcare assistant, this matters when you support children through their day. Write what you did, where it happened and why the work was useful.
A good example is a short account of how you plan activities and update parents. It shows real work rather than an empty claim. If you have not done that task, choose a different example from your own work.
