that this report card comment can be misconstrued

Talk to the teacher?
Sounds like they care.

Why do you not have access to her homework app? Contact the school and get access.

Stop avoiding the issue. You need to parent your child and get her to bed earlier and get her up for school.

Ffa some parent abdicate all responsibility and then complain when someone notices

When I am tired, I crave and eat more junk food - I wonder if that is what she is doing. I think the idea she needs to be online until 11 or 12 for homework is bs - either she does in which case there needs to be a discussion of why it is taking her so long. Or she is lying (which is not unusual at that age) and it needs to be nipped in the bud.

You don't have to be a doctor to worry about a child who seems out of sorts.

Are they reflecting back the lack of sleep and poor nutrition you raised with them?

ie we are all on the same page.

Honestly I have a kid that sleeps poorly - despite by best efforts - but I've never mentioned it to the school - same with diet - mine mostly went in with packed lunches but I expect as teens they did eat junk - so nutriention at home was upped - never expect the school to solve or mointor that for us.

Seem you raised these as issue so this teacher knows they are issues for this child - this may just be acknowledging that.

As someone who works in a secondary school i am assuming she is exhausted whilst there. I am also guessing she isn't learning anywhere near her capability because of it. I am also guesing she needs the Internet off earlier to get a proper sleep which they are trying to tell you. At 12 she probably needs to be asleep by about 10 pm to get adequate sleep.

The nutrition area baffles me unless she is coming in hungry from skipping breakfast and saying she us hungry of staff see signs she is.

But if you are the one notifying them of the issue what's the problem with them noting it on the report for DD to see?

It sounds like the inmates are running the asylum. For goodness sake, you are the PARENT. You cannot control everything she eats (where does she get the money for food at school?). Is it for an actual meal or snacks? If its snacks and you give her the money for it, stop. She is a child. She needs proper rest. I would die a thousand deaths if the school contacted me and said my child was falling asleep in class. You must be the topic of conversation of the teachers room.

Mine are older and school night it's 9.30 no more phones and such and in bed . Otherwise I take everything off them. Only had to do that once.
Also no social media . They never have used it.

I think the comment was actually meant for dd, it was trying to show her that she needs to be responsible for going to bed at an appropriate hour and making sure she eats well. Junk food (if she’s buying unhealthy foods at lunch time) will just make her feel more tired so I believe the teacher wants your dd to acknowledge this.

I wouldn’t say it’s personal next step against you as they would have discussed this previously. If she’s falling asleep in class then she’s most likely saying she didn’t go to bed till late or has barely slept.

I think the best thing to do is read the report card to your dd and highlight that the school have noticed the tiredness and want her to form a proper night time routine instead of staying up till late online.

I may be wrong, but one of your posts said you contacted the school that you were concerned about your daughter eating rubbish? The comments sound like they are trying to support you by mentioning this in the report. The comments are aimed at your daughter, not you.
You do sound quite passive about your daughter's behaviour. Emailing the teacher because she slept late is unusual. It sounds like you expect the teacher to deal with it, not you.
You need a chat with her where you discuss these comments, ask how she can help herself, tell her that you are going to have a new policy of WiFi off at nine thirty and bed by ten. Tell her you are both going to go on a healthy eating plan and enlist her help in choosing stuff for lunches.
Put the fear of your ex to one side. If he comments, then tell him you've already discussed it with your daughter and it's in hand

Internet and devices off at 9pm

Packed lunch at school

I read it that "key for dd to succeed..", means it's her responsibility to do those things. Report cards have targets and advice for the pupil, not the parents.

If the school thought that you weren't feeding her properly they wouldn't put that in the report card, they'd being having a conversation with you.

And you do seem to be sharing stuff with the school (which is good) but then becoming upset with them when they make it clear that it’s a problem. Remember they will be the ones dealing with her falling asleep or being irritable all day. I wouldn’t be emailing any teacher very late at night, it can wait or be scheduled to be sent in the morning.

Very odd thing to put on a report unless it’s some sort of school that’s got an obsession with being healthy and they write it for all. If I’m being honest they must have real concerns to write that unless they are very strange. Look inwards and reflect before you kick back. Is she overweight? And at nighttime it’s goodbye to any devices from now on. Lock them up if you have to. A sleep screensaver on YouTube only if she struggles to sleep without noise and you take the remote away. Take ownership here.

I’m not really that clear what you’re asking OP. You seem put out that school have recognised issues that you say are correct. And then worried your ex will use those reasons against you. Firstly, I wouldn’t even give his views any air time. He can step up in helping to educate your daughter to make better decisions if he’s not happy. Secondly, you can control some of this to an extent - why are you even letting your daughter stay up until that sort of time? I realise there’s not a lot you can do if she simply refuses to get into bed, but it doesn’t seem like you’ve tried - turn the router off earlier, encourage her to get into bed for a cuddle and a chat with you, read a fun magazine together or a book, like you would have done when she was little but make it more grown up. Do a face mask together or something if you have to, paint her toenails. Encourage her to wind down and hopefully she’ll sleep earlier. Good luck x

I'm a bit staggered that you wait til 11pm or eve midnight to take away the WiFi router OP. I'd be taking the power cable away from the computer and turning the WiFi off by 8.30pm and insisting on things like a shower and time spent chilling in their bedroom to wind down.

How could this be misconstrued? I think it’s pretty obvious what they mean here

You do realise that secondary school teachers can see hundreds of kids in one week and the report will mostly be a cut and paste job? YABU to read it as a personal slight.

If she is falling asleep at school sounds like a case of don’t shoot the messenger. The teacher is stating the obvious, you should listen.

If your DD is buying and eating crap at school you can easily prevent it by not putting money on her school account and sending her with healthy food instead. You can easily make something like a pasta or rice salad in bulk at the weekend, or sandwiches. The food in secondary schools is complete and utter junk generally.

If its reached the point school are actually commenting on your child's sleep and nutrition you seriously need to worry about that, and not how some words might be misconstrued!!

You seem so unconcerned that your child is falling asleep at school... That's not simple tiredness thats exhaustion and a real sign of major issues.

Where is she buying the junk food? Are you funding it and can you do something about that or is it bad choices about school lunches or not eating enough. Could be things you can control, money for junk food, or things you can't control like she won't eat her lunch. I agree it isn't very clear.

The mum emails the teacher when she goes to bed late

For the sake of what is documented and could be misconstrued by your ex, I would seek clarification about the comments from whoever wrote them. That said , in senior school I think it’s widely accepted that a child will participate in reading their own report and lifestyle choices are indeed integral to education prospects. It’s fair enough if this has already been discussed with school. You raised the concerns , and this is the right thing to do, you have recognised a problem and mentioned it to implement support structures. No professional could argue with you doing this, this is what a good parent does.

It would still have been appropriate for the teachers to speak with your parents about your constant tiredness and discuss a plan for your insomnia. Also the thing about yawning from boredom is quite a silly excuse...
