That's a lot of criteria to cover in one, does she want you to provide 1 plan in preparation to observe you in all these areas? I would think of an activity you could do with a small group of children, then look at which of these criteria you could cover with this activity. Write up your plan with step by step guidance on what you are going to do, then match it up to the criteria you need to achieve. You can then look at the criteria left over, and work out how you plan to achieve them. For instance, if you make up formula feeds, ask a colleague to sign a witness statement to say so, if not, then you could include it in a professional discussion with your assessor. I hope this makes sense, and has been some help. Taking it in bite sized chunks will help
