Question for Second, Third, More-Time Moms

I’m sure someone will get a kick out of this question, but...

At what point did you notice your toddler/child had enough independence to be able to play by themselves for a noticeable period of time (obviously you will still be in the room, but able to get other things done)? I feel as though I keep telling myself, “Once they roll over, once they sit independently, once they crawl, once they walk... etc.” and I’m not exactly sure when this will happen. I think the latest sleep regression/teething is getting to me😂
