Yes, time with dad. Get outside and walk or hike. Play in dirt. Explore plants and flowers. Splash in a creek. My daughter really enjoyed the affordable bow&arrow with foam target.
There is nothing my oldest (4.5 years old) enjoys more than going down to the creek by our house and exploring.
We’ve learned pretty quick with both kids that spending a lot of money on toys etc resulted in a lot of one-and-done play sessions before they’d quickly lose interest.
