Yanbu at all! I was going to send my own dc to school in a taxi today because of the snow but exdp (we live ten minutes away from each other) offered to take him before he went to work, without my intervention, so not complaining there!
Ds doesn't have any SEND but I have pretty severe adhd, which despite being medicated makes the festive period quite challenging for me personally. I've worked over Christmas too so haven't really had any breathing space.
I had Christmas eve and Christmas day off and hosted, then a wedding to attend over nye which was lovely but involved travelling to another city and staying in an air b&b with 12 other people for two nights so pretty exhausting, then just finished three 12 hour night shifts yesterday morning. Better believe I spent the vast majority of the day fast asleep while ds was with his father!
So today I'm very slowly trying to reset my house, tackle the mountain of laundry, take down the decorations etc. I'm on my third cup of coffee and have managed to put a single load of laundry on and come up with a vague plan of action. I'm back in work again tomorrow so only really have today to get it done.
I also have a pile of cardboard boxes, paper bags and wrapping paper bigger than me that I'm not even going to try and recycle. I'm going to burn it but the snow is very off putting.
Rest days are I'm op, don't let the naysayers tell you any different and enjoy your sweets and your duvet!
