Actually I'm not sure whether this is definitely worse than "having to think of something for dinner every damn day" but it's certainly close.
Honestly I've always found the general lack of freedom that comes with being a parent a reasonable trade-off - fewer spontaneous nights out, less time for myself, all of that. But one thing which is just...urgh...is when you're ill and you can't just sign off sick for the day.
I've taken a sick day from work today with a heavy cold. But I still needed to be up at 6am to get the kids up and sort breakfast and packed lunches, do the school run. I've gone back to bed now but will be back up later to do pick up, dinner, bath and bedtime.
Pre-DC I'd probably have just have had a slow start to the day, powered through a work day and then tucked myself up in bed with a lemsip, toast and boxset as soon as I was home. Or I'd have had a true duvet-day and not got out of my PJs at all. Sometimes DH can pick up the slack but it's difficult with his work and I'd have to be at death's door. I'd just like a day off to feel sorry for myself!
(and before anyone starts, yes I know there are many other things that could be much worse - I'm poorly and having a grumble!)
