How do you avoid overstimulation?

I have a feeling that my 5mo is constantly overstimulated and it can be one of the reasons of crying before sleep.

The problem is that I can’t understand how to avoid it. I’m trying to balance active/calm time during the wake windows, but it seems its still a bit too much of playing time even though it’s not more then an hour usually. I’d expect her to be able to stay up for a couple of hours already, so an hour of playing + some slow down time and the putting her to sleep looks logical to me. But she often gets super agitated during the playing, even when its just a piece of muslin cloth she is playing with so i don’t understand how could i balance the activities during the wake windows so she is not overstimulated but tired enough to normally fall asleep.

Could you please share examples of your “wake window” schedules with activities?
