I try to be very open and forgiving, as it's the same as what if I have a sick parent or spouse that I need to take care of. Same thing.
HOWEVER. I have a WFH job that is very heads down and forgiving on time, and most days we have 1, count it ONE meeting that lasts 15 minutes. A daily standup. I have coworkers with kids who miss it DAILY, usually because of childcare. How, how do you miss our ONE meeting? If your kids are at home then how do I trust that you are actually working most of the day if you can't set aside 15 minutes daily? If your kids need to be dropped off then I'm sorry but how does it take that exact 15 minute period every day? Can't drop them off 15 minutes earlier or later? (And yes, we've adjusted our daily times, but then after a month or so it starts happening again). To be fair I think they're just blaming the childcare.
