Thank you, all. Really

I feel better today after a full day at work
EightiesChick, oh, you insightful woman! I am very conflicted about the nanny-thing, not because of the reasons you are suspecting, but because I am dreading the conversation with our current CM. Whom I love. And the children love. Apart from that, I am very aware that with her providing child care for 4 children, what we pay her is a huge chunk of her family income. I keep chickening out of the necessary conversation and I do want to give her as much notice as I possibly can.
LuzLuz, I so totally and utterly agree with you: to raise a child takes a village. Sadly, we don't have one (v elderly MIL with strained relationship to DH and my parents/brother live abroad, no aunties/cousins etc). I am so glad that we at least live in a village were my older ones can go to friends' houses on their own, walk to school, go to the local park etc.
Amazingly, if they have friends round to our house, they often behave better. As if they were a bit more 'diluted'
. And I thought 4 ruddy children would jolly well be enough!!
Xenia, I was keen to be at home one further afternoon after school, partly because DS2 needs somebody breathing down his neck a bit of help with homework, and partly because there were issues with other children at the CM's. I DO like spending time with them when they are cooperative; not angels, but just not rotten to each other.
MissP, I love the inside/outside thing; v well put. I shall try to remember it. You of course have charming I. and don't know how I suffer 
ang, see, this is the beauty of MN: no subject too awkward to air and you'll always find somebody in the same/similar boat
.
And to everybody who said IABU: I fully accept your verdict that IABU to be envious. It is a pointless and negative emotion which makes you feel bad and does not change/improve anything. I shall try and desist.
And yes, DSs are/look absolutely angelic when asleep in their beds - I will go and sniff their heads
