Very bad runny nose, do you call parents ???

[DisneyPrincess]

That was suppose to be posted yesterday but didnt know how it worked :
Ok so I had a situation this morning. One of my daycare kid (21 month old little girl) started a bad runny nose yesterday. I wiped her nose easily every 5 minutes, screaming and crying her head off every time, even scratching me to stop me. She ended the day with a red nose, red checks and reddish around her mouth. Obviously she was starting to get sick. This morning they brought her in, I did say that if she would get more sick, I will call them and he agreed no problem. She seemed fine, although I would find odd that she's not sick anymore. As I suspected, one hour later.. not even, I called the parents to pick her up. Her runny nose was so bad, thick, between clear and yellowish, she was wiping her face with her arms and hands, it was all over. Every moment here and there sneazing and big chunks came out down to her chin almost. She also started coughing, her nose and cheeks were red and around her mouth as well and her eyes were watery. Although smile, she was sitting in her chair zoned out. When the father arrived he was really pissed off, saying this is the second time I call them to pick her up (last time was 3 months ago), and he said that they might find alternative if this is how I work (meaning finding another daycare) I said I understood completely, that I will not call for just a runny nose, I have had runny nose quite often in the daycare and never called because... it is normal, it will happen I know that. I have been very sick also quite often and still keep the daycare open to take care of their kids. I dont specify anything about cough in my contract because it is to elaborate, its really about common sense and the well being of the child, the other kids in the daycare and me as well. I am very bad at confrontations, I get really stressed out and can not find the right arguments to prove my point when face to face. I find myself to usually being very kind, calm and understanding with the parents, I listen to them and I do the best I can, but now I feel disrespect a lot. Anyways, that said, I need you guys opinions : WHAT DO YOU THINK OF THAT SITUATION, WHAT WOULD YOU DO ?? DO YOU SPECIFY ANYTHING ON THAT SUBJECT IN YOUR CONTRACTS ?? SHOUD I WRITE A EMAIL TO ALL PARENTS TO BE ALL ON THE SAME PAGE ABOUT THIS ?? Oh please help me soon thank you. -------- today being the day after this episode, they kept her at home and I dont even know if they will come pay me for the week (I texted them the message to please not forget the payment today).
