When do you stop using stroller with your child?

For my older daughter, I stopped at about 2 years old when she was able to walk and run much more confidence. I didn't want to spoil her by pushing her everywhere and would rather her be walking and exploring areas on her own (within my sight of course). If she needs a nap, I'd usually go to a nearby cafe to chill while she sleeps on my lap. It works perfectly fine for me coz I get to eat and rest too
