No that's not okay and I would suggest you address it with management.
Hey really sorry to hear your nursery is like this, so my boy started when 8 months old and is in 4 days a week and they follow his routine to a T, some days are different ofcourse but they regularly ask me if any changes in routine at home, only issue I ever had with them was when I dropped his afternoon bottle as he was refusing lunch etc and was advised to do so they kept giving him it and then the HV at the review said it needed dropping fully they then listened xx
This is happening to me right now too and she literally looks sick when I collect her .. she’ll sleep in the car on the way home at like 6pm and all eve she’s so upset and miserable cos it’s not enough !
