God, I wrote an essay sorry! But having had a little window into the inside workings of a couple of nurseries recently and being shocked by what I saw, I felt compelled to comment. A few months ago started a role (I didn't last!) where the manager told me about the fact there were less requirements now for paper work (OP, people are not making this up!) yet in the day to day running of the class, keyworkers (who counted towards ratios and were actively "working" with children) would be constantly tapping on iPads and ignoring the kids. If that's what it's like with less requirements for documentation, I'd hate to see what it was like before! Another nursery I was in had set up an Instagram type photo op for a sensory activity but the only engagement with the children whilst they took part was asking them to smile for the camera.
When I visited the nursery my child now goes to and they told me that they don't have Tapestry (it's all on paper) and each keyworker has an afternoon a week non contact time timetabled for admin I practically bit their hand off!!
It's clear you are angry about paying more for what you perceive as less of a service...
Firstly have you broken it down as to why things now cost more? Cost of staffing has increased (given a lot of nursery staff will be minimum wage). Running costs have increased with energy price rises, food prices etc so this alone would be enough to raise fees without putting any money into the staffing pot.
With regards to understanding why they now "don't have time" to take photos when they did before... There's a number of factors. If they've taken on the new ratios, regardless of if you perceive it as a small change, a member of staff could still be be doing 125% of what they used to (for under 3s). Staffing could have changed. If they employ a teacher in 3+/preschool, they could have 13 kids to look after instead of a previously less qualified member looking after 8. Not to mention that whilst the smaller numbers might be supervised (in ratio) by one member of staff (who might be able to take photos), a different keyworker could be responsible for the admin and uploading of said photos for a significantly larger number of children. Unless you know the qualifications/child allocations for every member of staff, it makes no sense to be thinking the way you are. Also, whilst I'm talking about staffing, you may or may not be aware of the recruitment crisis in this particular sector. If the nursery were previously able to timetable non contact time for admin but have now lost a member of staff (which they might very well struggle to replace), they might still be able to keep up with the legal ratios but only by reducing non contact time... Which would obviously mean less time free to send photos!! Another possibility is that they might have decided to change their working practice and be having staff set up more planned activities per day, they may have started placing more emphasis on interaction with the children. Staff illness is another consideration. Whomever you spoke to at the nursery probably didn't feel they had to explain things in minute detail and felt that they "didn't have time" would suffice. I'm sure you could ask for a break down as to what changes have made time become so limited (but as others have said, that would be putting you in the "that parent" sort of category...).
The one thing I can sort of agree with is it being frustrating when your child only turns up on a couple out of over a hundred group photos. A few things to consider. Firstly, if they're talking group shots to save time, they are not going to be ticking off how many photos they have containing X child so this can happen (not exactly a flawless method). Secondly, it depends who is taking the photos and for what purpose - your child might not have wanted to do the activity being photographed etc. Thirdly, some kids are lovers of the camera and some aren't so getting photos will be easier or harder depending on personality. What I don't think would be totally out of order is mentioning that you didn't see many photos of your child in the update and you're concerned she's not enjoying herself at the moment and see what they say. I know a lot of professionals that bristle when these things are mentioned but if I'd consistently managed to miss out a specific child, I would want to make sure that changed going forward. Depends what your nursery is like tbh as to how the staff would take that. Basically I don't think you can complain about them doing things differently now but having a discussion about your child's happiness and absence from the photos would seem sensible. If you're genuinely still concerned after having that discussion, then look to move her! Its all personal taste and how your child fits in in a certain setting. Settings can and do change over time.
Also (if you made it this far! 😅), I'm not in a nursery now but can I just say to everyone saying it takes 5 seconds to take a photo (and the others who are saying its more the admin than anything else as photos are quick to take) - I am in awe that people are able to do this for each individual child multiple times a day! I honestly find it so hard to take photos and with thirteen 3 year olds to keep eyes on it's like herding kittens!!! I honestly never had a second. And if you're one that's commented about teachers being lethargic and doing nothing, I honestly wouldn't be using that nursery!
