Activity ideas for assessment

[Cori21]

I am being assessed in placement soon with babies (under 12 months) and I have to plan an activity to do with cognitive. I know this involves anything but I am struggling for ideas due to the age of the children. There will only be 5 babies maximum between 8 months and 12 months. I was going to sing songs to them but the EYP said they won't sit and listen. I want to do something different though rather than just singing. I only need to plan one activity but the assessor stays for an hour so I will probably need to do a few things!
