So many accidents at nursery!!

[dabbitydibbity]

My DS1 has been potty trained now since the beginning of June. He picked it up remarkably fast, with only a handful of accidents to date from day 2 onwards. He is only 26 months old so we've been impressed at how well he has coped. He will say "oh pee pee" when he needs to go and will willingly use the toilet at home or out and about.
He has recently returned to nursery after the 8 weeks of Summer and unfortunately he is not managing to go a day without at least three or four accidents. He's only there two days a week and these accidents only ever happen in nursery. He's not regressed one bit at home so it's a source of frustration for me. I'm sure he is just needing time to settle as he has moved into the 2-3 year old room so it's all change and clearly he needs time to adapt. The nursery girls have been taking him to the toilet regularly and he sits but does nothing. Ten mins later he will have an accident. Then another. Then another! It's at the stage where he's only managing one toilet trip successfully the whole day he is there. I just don't understand it! Why isn't he telling them he needs to go?! And if he's too shy, why isn't he trying to go to the toilet himself like he does at home? I'm maybe expecting too much of such a young boy but I'm not sure how I can help change the behaviour as he doesn't do this at home so I can't even reinforce their efforts to help. Twice now I've turned up and they've put him in pull ups as he has gone through all four spare pants changes.
Has anyone else had a similar experience with their little ones? Any tips or advice that you can share?! Is this just a phase?!!

I am going through something similar with my son at the minute, he is 3 and started nursery for the first time 2 weeks ago. Fully potty trained at home but the complete opposite at nursery!
We have had a break through today though, I sent his toilet seat to nursery with him, something familiar in the toilets seemed to work! He came home with 2 stickers on his jumper (one for each time he used the loo) fingers crossed for tomorrow.

Nursery girls?

Yes nursery girls

My daughter is 3 and going through similar. We think it's down to her being shy and not wanting to ask. We are rewarding her if she has a day at preschool with no accidents.

If I was a nursery worker I would be if you called me a nursery girl. Would you call a doctor a 'medical girl' or teacher similar?

I'm also going to jump on the op for the use of nursery girls
It's patronising and gives the impression that you look down on them, because they are just girls, not proper adults doing a professional, skilled job
My nursery staff have degrees and I also employ a man. Would he be a nursery boy?
As for the problem with the accidents, I think you just need to ride it out and let him settle back in. It is still early days, but maybe suggest they stop taking him to the toilet and only take him when he asks to go

Do the setting offer any other ways for child to communicate their need for the toilet for example a symbol card he can point to or take to an adult? Or if the toilets are outside of the main nursery room a place he could stand near the door to them?

Is there anything you are doing for him in the toilet that they wouldn't do in nursery? For example I have known little boys whose parents use their own finger to keep things pointing down rather than teaching the boy to do it themselves.

For goodness sake, people are really overly sensitive these days! Nursery girls is a term the staff have used themselves when referring to each other! At pick up and drop off times they've mentioned how the other 'girls' have noticed he did this and one of the 'girls' took him to do that etc so I wouldn't be so hasty to pick up on my use of language.
Needless to say, my original issue (before this became a political correctness rally) has now been resolved after taking his own potty in to the nursery.
