OH was off work today ill, and DD's (6yrs - not in school, live abroad) daycare was shut so she stayed home with him while I went to work. The other employee couldn't come in so instead of my usual 3 hours I stayed all day to help out and got home about 4 o'clock and found DD sat on the sofa watching cartoons on the iPad, still in her knickers (so hadn't got dressed yet at all).
I don't expect him to entertain her, especially as he's ill, but she can and will go and play happily outside or in the playroom if you just tell her to switch off the cartoons, but if you don't tell her she'll watch for hours like a zombie. So he had just not bothered to tell her to go do something else all day - he's not even that ill, just a bad cold, he was well enough to sit at the computer watching films.
I cannot be unreasonable to expect him to make her go play or get some fresh air at some point during the day, right??! She switched off the cartoons the moment I told her and went outside happily enough, its not like its a big ask.
