NC for this just in case. 
So we have a ds who's 4. Friends have ds 4 and ds 2.5. We all hang out together a lot.
Friend is always super tidy. Kids have very few toys (fine btw, ds has too much and I'm in the process of paring down) and they are organised impeccably. (I also like to keep ds's toys very organised, not a problem.)
But when we go to play, even if there are other kids there too, only one toy is allowed to be out at once. If the kids want to get another toy out they all need to put the toy that's put away first. I agree with this to an extent. If ds tips a bunch of stuff out or get his marble maze out or whatever he's not just allowed to tear through toys until everything is out.
If they ever ask to get puzzles or duplo etc out they get told it just for special times and is too much mess.
It puts me on edge the whole bloody time because she stomps around morning about how things aren't in their right place.
Last time we were there she told dh off for eating take away on the sofa (they have open plan living room kitchen diner thing.) Dh was really embarrassed and annoyed. He's an adult he doesn't tend to spill his food. (Unless drunk
.)
I was saying how ds got a load of Lego fro Christmas and she said 'oh we'll never be letting the kids get Lego, it's way too much mess to tidy up.'
She also won't let them do any painting or arts and crafts at home apart from pencil drawing. Because 'my furniture is too nice for stuff like that.' Obviously I'd love to ban painting and such too as it is a massive sodding mess but they need to do stuff like this no?
Is this how most people do things? I thought I was pretty uptight about tidiness and cleanliness as I've suffer from OCD and anxiety at times and have battled to lighten up on the mess ds and dh make and see them as normal life rather than getting me in to a downwards spiral of organising and cleaning.
I'll make ds clean up a little as he goes along in the day and tidy toys away at the end. Have I let go too much?!
