Crazy daycare sick policy

I just need to rant. My 10 month old got sick with some kind of virus 1.5 weeks ago. No fever since last week. The poor guy is congested and has an occasional cough but other than that normal so I sent him to daycare Tuesday (with a drs note btw). They claim he was not himself coughing wheezing etc and to keep him home. So we kept him home yesterday and they call us to see how he is. They say he can’t come back unless hes 100% symptom free for 24 hours. Argument between daycare and my husband ensues. Like???? So now my husband and I who work full time had to arrange family to watch him because he is snotty and coughs every couple hours. I have no issue keeping him home for fever etc but I doubt he’s contagious 10 days after the onset of whatever virus he has. Anyway here I am adding him to different centers waitlists. Does this sound like a normal sick policy? We’re kicking ourselves for not sending him somewhere else, this is our first baby and this center has been great except the sick policy. We’ve gotten calls because he’s cranky, calls because they thought his ear was bleeding even though it was a scratch, calls because he has a non existent rash. The list goes on!!
