For context school would have finished at 11.40 on the day in question (Scotland).
On this particular night, DD5 was tossing and turning, wimpering and coughing throughout the night which is usually a sign that she's starting tonsillitis which she gets a lot and quite severely. When I went to check on her at 5 am she was miserable, and asked for water and medicine which I gave her. No vomiting, no fever. She tossed and turned and coughed for another hour before falling asleep just before we would normally be getting up. I decided to let her doze a bit but when after an hour she was still in deep sleep, I made a judgemment call and messaged the school to say she wouldn't be in - probably the start of tonsillitis again. However, at 9.30 she woke up feeling perfectly fine and with no recollection of ever being unwell during the night. She's angry and upset that she's missing school. I felt it was too late now to take her. I thought it would be awkward and disruptive for the teacher if I took her halfway through the morning and an hour before finishing.
Ex DP had her that afternoon and thought I'd been massively unreasonable to keep her off that morning. She just had very mild 'sniffles' at that point and was fine at her club.
What would you have done that morning? Was I unreasonable to keep her off?
