Ideas what to do with toddler

[SpongeCake23]

Sorry if already been asked.
We live in a small house, one big room for eating and living area. One small kitchen downstairs. No room for a table.
We have a tiny yard.
There’s upstairs too but my DS is only 17 months so he won’t be going up unsupervised.

We live rurally so will be going for walks away from other people and if we see a dog walker, will keep our distance.

But can I please have some ideas for indoor play?

How tiny us the yard? We have a small shaded yard and have small table and chairs, sandpit and few plants, outdoor candles and fairy lights, my kids love it they use chalks and I have a tray that is 1 metre across 1 metre down that I've filled with water and toy sea animals. My yard is really small you couldn't swing a cat but you will be surprised just how nice you can make a small space
