morning all, sad though I am to hear some of your stories, I'm glad it's not just us that get the small petty snarky moans!
To address some of the above points:
@AnneLovesGilbert - She doesn't have my number, she texts my OH - he usually doesn't tell me anything she's said, but sometimes it's just so ridiculous that he needs to share! I am very glad I'm not her - it must be utterly exhausting getting in a state about every little thing.
arrangements He has them every other weekend, 1 overnight during the week and half school holidays - and that's after fighting through the court as Mum wanted him to have them less. (and obvs pay more!)
Missing things - usually we literally count every belonging in and out of the house to avoid any drama, however the kids are getting older now (10 and 13) and we do sometimes (gasp!) leave them to their own devices for dressing/undressing, and allowing them to pack their own stuff, with reminders to make sure they have everything. I see this as a vital life lesson - if you don't look after your things...
Homework - my OH has recently been into school as there is a concern that 13YO SC is falling behind and not getting enough help. The school had no idea they were struggling as Mum was essentially spending hours and hours every week trying to do all the homework with them (never trusted Dad to do any with them) and eventually getting frustrated and doing it herself or telling them what to write, and obviously getting it 100% right.
Now Dad has been allowed to get involved - so when with us, as recommended by the teacher, they now get a time limit. First they have a go themselves, then we talk about it, explain if necessary and get them to have a final go themselves - at the end of the time limit it gets handed in as it is so the teacher has an accurate impression of what the child can/can't do. If there is still a wrong answer, it stays wrong.
@BikeRunSki - I'm sorry you had to go through that drama as a child! We don't complain about her complaints - she would love nothing more than to get into a row about something... in fact anything! my OH doesn't even reply to her messages at all any more, which I'm sure enrages her even more!
@Brollywasntneededafterall - haha! love this - I think Mum thinks I'm slowly turning her children feral as I'm an outdoorsy type! we've had to buy them wellies and dark coloured leggings/trousers as the kids were terrified of getting Mum's clothes wet/muddy!
@lovelovelove2 - my OH is also not allowed to wash their clothes any more, apparently he also cannot be trusted to work a washing machine.
@Nowomenaroundeh - that sounds awful! thankfully we don't have that - Mum won't ring, only communicates by text, but does constantly text children when they are not with her, which gets slightly irritating - thankfully kids are rubbish at remembering to take their phones out with them so we don't get days spoiled by her.
@Coffeey - whoah - you barreled way over the line with the whole roast dinner thing! 
how dare you feed the children a lovely meal?! they should be getting gruel cooked by their father and be grateful for it!
I'm a pretty good cook, I usually cook from scratch, even while the children are there - the youngest loves to help (I know cooking for the kids should be my OH responsibility, but I actually enjoy it!) one of them went home previously saying "Nina made the BEST spaghetti bolognese" which apparently went down like a cup of sick!
@ImitationofBeing - we had a similar incident with things in pockets for this weeks Sunday night moan! - items are not allowed to move between houses (at Mum's request) and SC had accidentally left several fidget toys in the pocket of a pair of trousers I can guarantee these will be sent back with the children next time along with a curt note asking for items to remain in their respective houses!
Watch this space for next weeks exciting episode...!
