To take an extra sibling if not allowed? Super Selective Grammar School visit.

Year 2 then.

You’re clearly making arguments against every suggestion, so I’m assuming you all just want to go as a family day out.

the fact you’re asking here, instead of ringing the school and asking them shows you don’t want the actual answer, which is of course not to bring your other child.

Meanwhile in teletubbtland people are getting ready for another really hard week ffs who cares

We have the same with Nonsuch in early July, although we have managed to sort childcare. It's frustrating, but I understand they can let more families in by limiting it to 3 per family. What is more annoying for me is that the Nonsuch open 'evening' is actually in the afternoon, with the last slot being 5:15pm, so we both have had to take an afternoon off work. I'm tempted to scrap applying there, which is sort of the point. They are so oversubscribed they don't really care if some people struggle to attend.

An anecdote from an independent school is irrelevant here. State schools have to follow the statutory School Admissions Code.

And in the very unlikely event that this does not break the tie, there is an independently supervised ballot. It is explicitly stated in the admissions policy: www.wilsons.school/admissions-criteria/

Organise a playdate or ask a friend to babysit?

This
open evenings with mum, dad, siblings and sometimes grandparents too are utterly ridiculous
are people not capable of making a decision on their own?

I would go but be prepared if they say no. Some people will not turn up on the day

Yes you are being unreasonable. Do you know anyone else who is going who doesn’t need all 3 tickets?

Oh what a lot of hand wringing. I’d just get on with it and make sure the younger kid sits on your lap for the talk

That is correct. But if two or more children get the same score then the one with the tricky parent might well be the one who isn’t given the place.
It’s not rocket science: just follow the rules!

It is very likely that multiple children will get the same test score. At that point some other factor does come into play. Perhaps it will be completely randomized or perhaps knowing that one set of parents is unlikely to follow school rules will make the difference.

One of you needs to stay home.

How about asking at your wrap around care, if any of their staff do babysitting, @NameChanger206?

If they were to do this (and I have no idea if they would or not), it would be more the parents have marked themselves out as difficult and a family who aren't necessarily going to abide by school rules or parents who assume that the rules don't apply to them or their child if they don't want them too.

In terms of first impressions, it wouldn't be a good one.

Ultimately, it's up to the OP if she follows the rules (or suggestions to call) or not but IME, schools that don't uphold their own rules in one area tend to be a bit 'flexible' in others too and not necessarily in the way parents would want.

I really really hope what you are saying here is not true.

It would be truly appalling if grammar schools were flouting the rules and not selecting on ability (and other published criteria).

Easy, just one parent goes. Why don’t both need to visit? Surely you trust each other. Exh didn’t visit any schools, he trusted me

3 tickets
3 people
obviously DON'T

In this case, no, it was an independent, but however many rules there are for a state grammar, all the people doing the selection have to do is state, truthfully, that they have filled all available places.

Was this a state grammar?

I can also support @Macaroni46 's assertion. At the last school where I taught, we had an activity morning for prospective pupils, and they were observed as they participated in a Games session, an IT session, an Art session and a Music session.
As you can imagine, these are parts of a normal school day where youngsters show up in their true colours, and if you are choosing between two children, their reaction to slightly more freedom can be telling....

It doesn't work like this any more (if it ever did). State schools have very particular rules to follow (even grammars) and could not possibly use "brought an extra child to an open evening" as a reason to exclude.

At this early stage in your relationship with the school, I feel it would be unwise to self-identify as That Parent.......after all, the school is, as you say, highly selective, so taking their pick.
A cautionary tale from many decades ago. A girl in my class, as clever if not cleverer than me, was going for the most sought-after grammar school locally, (back in the day when little Londoners still sat the 11+). She was quite a mousy little thing, probably because her DM was, er, strong minded. It was one of the "baby bulge" years, and the headmaster advised my parents that the competition would be particularly tough numbers wise, recommending a slightly less prestigious grammar school, which worked out well for me.
My classmate's DM forged ahead regardless, and then insisted on sitting in on her daughter's interview with a member of staff, which was apparently part of the school's admission policy. Having thus thoroughly drawn attention to herself, she was livid when other girls gained places while her daughter didn't, to the extent of berating some other parents. I don't know where she ended up going.
