I was wondering if there ever is an instance where you don't call parents to pick up a sick child or if you always do.

I have a 17 month old today that has had very watery poops. 2 this morning and then one just as she got up from nap (this child is always a pooping machine lol other than never this watery). My policy states that after 3x then I call them to go home. She is a little crankier than usual and has had a cold (was home sick on Friday). Is there ever a time when you don't call for pickup as it is almost the end of the day anyways?

Just wondering. I texted mom and she should be here shortly.
