DS won't use potty at nursery

[Chocolatestain]

DS is 2 and 9 months and we have recently started potty training. He is doing well at home and at using the travel potty when we're out, but he gets very distressed at nursery and refuses to go on the potty at all. He goes to nursery from 9-4 on Mondays and 9-1 on Thursdays. He loves going, is happy to have his lunch and nap there, and the staff are very supportive. He has been to nursery twice since we started potty training and both times he has held his wee in until he ends up having a small accident, which turns into lots of small accidents because he doesn't go fully each time. Whenever he is asked if he needs to use the potty he says 'I went at home' or 'I'll go when I get home'. I tried taking his Thomas the Tank Engine potty from home in and the staff put it next to his friend's potty from home so they had their potties together, but it made no difference.

The nursery staff are very patient about all the mopping up, but their concern, and mine, is that DS is getting very distressed about it all the accidents. He won't be going tomorrow because of the bank holiday and I'm not sure how best to handle Thursday. He will be moving, with the rest of his peers into a new group (totally forgot about that when planning when to start the potty training) although, fortunately, his current key worker will be moving groups with them. I hadn't planned to use pull-ups as I don't think they're helpful generally, but I'm wondering if it might be best to put him in them just for nursery until he is confident to go on the potty there. Any advice?

Does he not have access to a toilet rather than a potty at nursery.

my first thought would be is it dirty or smelly Or does it stink of bleach or cleaner.

is it in a place which is too public or draughty etc

What I mean is without ruling out resins why He won't go these reasons won't change and could still cause the same problem further down the Line and hinder progress at home

He has access to a toilet at nursery, but he's not very keen on the toilet at the moment, even at home. It's in the same area as the nappy changing unit, which he his familiar and comfortable with (and is perfectly clean and pleasant). My thoughts are that either he's just not used to the concept of people going to the toilet at nursery - he's used to being in the bathroom at home with me and coming with me into public loos - or that he's not feeling fully confident about potty training yet and doesn't want to try with anyone other than DH and I. I'll see if I can gently prise any more information out of him - he hasn't been very forthcoming so far.
