Tree, I hear you. I hate it when weekends go down the toilet and I have always hated Sundays in general, so when they go to pot it always gives me a major downer.
Can you perhaps do something nice after school one day to make up for it? Nothing fancy, just a simple treat. My boys always love it if we have a little tea party after school with them having a huge slice of homemade cake and a big glass of milk, would something like that redress the balance a bit? Having girls you could maybe do the doilies, napkins and fresh flowers thing as well to make it more special. Then you could plan to have your quiet evening with dh later on. I think weekends are overrated and we often end up neglecting the other evenings in the week as a result.
I know its no consolation, but my weekend has been crap too. No vanfest as ds2 is a limp dishrag, although thankfully not puking anymore. Definitely not fit for school tomorrow though.
Hope you manage to salvage something of this evening for yourself. x
I am nervy tonight as ds1 has his first swimming lesson with the school tomorrow afternoon. He is really excited, but I'm worried how he's going to cope with all the self-management involved. We have had several dry runs of the old 'getting the pants on and off under the towel' routine and he's practised getting his swimming cap on and off a few times. The swimming cap practise came with many outbursts and much sobbing, as one of his worst sensory things is around his hair. The slightest pull on his hair and he's screaming in pain, but will he have his hair cut short? Nope. 
Fortunately I spoke with one of his teachers about this on Friday when I found out long-haired boys need to wear caps and she said they'd make sure the accompanying staff and pool staff were made aware it might be a problem. I gave him the option yesterday of either having his hair cut, or buying a cap and he went for the cap. There are several boys with long hair though, including the boy that bullies him, so at least he won't be the only boy wearing one.
He has also announced that he wants to go on the Year 4 outward bounds residential trip next April. I have been dreading this since he started school fgs. The Head emphasized how the trip encourages independence and self-management skills and how the pupils won't be spoon fed while they are there and I'm not really sure if ds will cope to be honest. Initially he said he didn't want to go as it wasn't his sort of thing, but then he went to school and all the other kids were talking and getting excited about it and he changed his mind. He really wants to do archery and the underground maze/artificial caving. The teacher who has a son of her own with ASD is accompanying the trip though, so at least he will have one advocate there. We have to pay a £50 non-refundable deposit straight away, then another £150 in stages. If he changes his mind within 69 days of the trip we lose the lot!
