Feel free to add any ideas you have. If you have a question about activity time, please create a new post outside of this post. The activities listed are just ideas on what you can start working on, it's by no means an expectation that your lo will be able to do them all at this stage - it's just something interesting they can be introduced to ie. stacking blocks, posting shapes, making sounds etc.
Stacking blocks/balls/rings
Posting items into different containers with different size holes
Shape blocks put into slots
Rolling balls
Reading
Making lots of noise - xylophone, electronic music toys, banging blocks, metal bowls etc
Teach how to go down stairs and off couchs/beds backwards
Push type toys
Walk behind trolleys
Making animal sounds and match it up with toy animals
Exploring their outside environment - grass, leaves, trees, flowers
Name everything you offer as food, where you're going, the car, door, keys etc and if you want to do sign-language, it's a good time to do it.
A lot of activity time will likely be through moving around their environment (crawling, standing, climbing), so most of the household providing it's safe will likely make up the majority of a baby's day at this age.
