How much do you really play with your kids?

Im a teacher and most of the kids in my class say their parents NEVER play with them, to me that’s odd. I always have gotten down on the ground and played, gotten into superhero costumes to battle my oldest son, built lego sets, wrestled, colored, etc. But when my one and a half year old naps, my husbands at work, and my four and a half year old is awake...is it wrong I want time to myself? I mean, I’m here obviously. And ya I don’t spend the entire day doing laundry, cleaning, organizing etc but I do like to have a break. I DO play with him, we’re doing Duplo Legos now, but am I terrible for saying ‘hey sweetie mommy needs a little break can you play something by yourself for a little bit?’ I don’t know why I have such guilt. Someone ease my mind or tell me I’m a terrible mother. My anxiety is insane over

this issue. I always feel like it’s never enough. 😅
