Easy activities for my toddler

I am due December 1st with baby #2! My husband will be home for the first week, maybe two, and then it will just be me and the kids. My daughter will be 3. I am expecting to be exhausted for the first few months and so I’m trying to think of some activities I can have on hand that are easy to pull out for my daughter that will give her some entertainment when I’m too tired to give her a lot of individual attention. Any ideas?!
