Nursery nappy changing issues

[NomNomNom]

Hi,

I need some opinions in order to decide if I'm worrying too much.

DD (nearly 2) goes to a nursery which has a great reputation, it is generally brilliant, the staff are on the whole friendly, lovely to DD, seem to cuddle her quite a bit, great activities, ok food, she loves it and gets excited when I mention going to nursery in the morning.

She recently changed groups to be with older children, and since then about once a week on average I realise when we get home that she has a pooey nappy. (I can tell when she has a poo, so it doesn't happen on the way home.)

Since the weekend she's had the worst nappyrash she's ever had. I mentioned it at nursery yesterday when dropping her off so they could perhaps change her nappy an extra time or something. When I picked her up after lunch, she had had a poo (only saw at home). Same today. So of course her rash isn't getting better despite the effort I put in when we're at home.

Does this kind of thing just happen in nurseries? Should I check her nappy when I pick her up and change it myself there and then if she's had a poo and they haven't changed her, or is that passive aggressive? Should I say something or give them a few weeks and see what happens?

(She's my pfb, so I'm never quite sure what I can reasonably expect.)

We got into the habit of checking and if my son wasn't clean we asked them to change him so he didn't sit in it in the car. It happened too frequently for my liking and he very obviously smelled. On occasion he would have the same nappy on all day as well.
In the end though we moved him to another setting (there were a few reasons for this, not just the nappy thing, but I think It can be a sign of other issues - staff were often stood round gossiping or crowded round a laptop which suggests to me that they weren't keeping a close eye on the kids).
