To think it's very rude to ring somebody at 7.30 in the morning

Depends entirely on context.

I think it’s absolutely fine for a nurse to call you at 7.30.

Sorry misread! Nursery, not so much. That would annoy me.

She said nursery, not nurse.

They will be calling before all kids in as have ratios to stick to. Tabu.

It's a bit early but they probably had a, list of stuff to do. They could have emailed. Surely you are awake though with a child that young.

you have young children & weren't awake by 7:30am? Lucky you!

Depends why/ what the schedule is of person being called as it may be a good time to chat to someone who does nights but yes, generally unless it's an emergency or at least urgent (e.g. so sorry but I can't open the rota and can't remember whether you are opening up the shop today or me) then it's too early. My mum doesn't necessarily agree!!

Definitely rude. 9am-7.30/8pm are calling hours in my book. The later evening ones depends on who it is! But if the question could have waited, 7.30 is definitely too early.

Don’t answer then.
It’s a request, not a demand

Is your child normally in and wasn't in?

Otherwise no it's too early!

I'm a teacher and we don't start our welfare calls until 10am.

Cross post! That's quite early yes

Put your phone on silent?

Agree, OP. Same applies to after 8pm - I instantly think it’s bad news then get annoyed for the disturbance to my tv time 😤

I think most people would answer a call from their child's nursery at that time thinking it was something urgent e.g the heating wasn't working so nursery was closed.

I'd not be impressed with an unimportant call at that time.

If they know that then I would make sure dh number is first on the list and ask them to put a note not to call you early.

It's not as simple as just 'dont answer then'. It's highly likely this call woke up the OP's baby, thus completely ruining any chance of making up for lost sleep through the night. OP you are not being unreasonable at all, but all the natural early risers will say you are.

The thought of being wound up enough about this to start a thread on mumsnet is comical to me. I suppose it’s all relative, so whilst I don’t think YABU to be a bit annoyed if you were woken from sleep, I do think YABU to think it’s such a terribly rude thing for the nursery to have done. Presumably the nursery have fewer kids in at that point and can attend to things like calls more easily then? Seems perfectly fine to me.

Well you know from now on to turn your phone to silent when you want to sleep.
Or you could continue being determined to remain angry about this and let it ruin your morning.
