DS has been going for a week of half days and no accidents, though I did tell them he was at nursery. Today was his first full days and as soon as I collected him the smell would have knocked you sideways! I had DS 2 (2) and DS3 (10w) so just went to the car thinking he must have just had an accident, but when I peeled off his trousers he was covered. It was all over his shoes, his socks, on the back of his trousers (you could see it soaked through, like he had sat in a muddy puddle) and once I wiped away the wet stuff, his legs were totally caked in dry poo, it had obviously been there hours. Half a pack of wipes wouldn't even get it off so had to put on his spare jogging bottoms and take him home for a wash (5 min drive). I asked him when he pooed and he said at lunch and when he was running outside. I can understand a missed wee as it can sometimes be harder to spot, but his trousers were soaked in shit and he stank.
They also 'lost' most the parents emergency contact forms (a teacher came out and accused alot of them of not giving them in - which in itself was only spotted after a week! and it transpired they had lost them and found them the next day)
I sent DS back in the pther day to get his indoor shoes and the teacher came back out saying he had to keep one pair there (I said I wanted them home to clean them, but infact I want to keep track of them) and DS blurted out they were lost - £40 and lost within a few days, but have given them the benefit of the doubt that they are just misplaced for a bit - they are very well labelled. They are supposed to have indoor and outdoor shoes, but after the first few days they said they weren't enofrcing it for a while to let them settle in 
Last few are just side issues as it seems to be one thing after another at the moment.
WWYD about DS coming home in this state?
