over a bloody booster seat 🥵

My 9 year old is being taken to a party in Manchester (1 hour journey) today by the birthday girls parents. She is 134cm (she’s a bit less actually but because her Dad told her she’s that, she’s sticking to it)

Sges currently sobbing and shouting (since 7am off & on) because I’m insisting she has her booster seat when all the other 7 kids won’t have one. She said she’s going to get laughed at and she just wants to fit in & be the same. I’ve tried to be understanding, I’ve said blame it on me, I’ve said they’re not good friends etc.

AIBU to stick to my rule? She’s nearly there but technically still needs a booster until 135cm. I’m just worn down as she’s been crying over this ALL morning🙄

Have a word with the parent taking them.

When my daughter was officially tall enough, she still preferred to use a booster in the front for comfort/better view. When I gave her friends a lift, I just said to the smaller one "why don't you sit in the front?" The booster was already there, no embarrassment.

It's likely the family still have a booster seat - it's easy enough to have one that happens to be already in the car - so someone has to sit on it.

They have a booster seat in the car for a 4 year old cousin but their daughter hasn’t used a booster in a few years, she just gets in and wears seatbelt🙄

I do agree with you, I do. I hate that I’ve let her go without it. I was very torn but she’s having ongoing issues with some of these shitty girls and I didn’t want her to be bullied for it. But I can’t say I disagree with you.

If the girls are this mean, surely they will just find something else to pick on her for. They don't sound very nice and at that age if asking why she still needs a car seat should be able to understand the rules and safety.

What's the party? Hope that doesn't have a height limit as while you have let this go, if the activity has strict guidance on height they will not be so lenient and have to abide by whatever rule is in place.

Namechangedforthis25 · 06/12/2025 10:41

On this. Who cares if you are the minority

the kids are old enough to understand. And embarrassment should not trump safety

these other replies are mind blowing to me

Totally agree with you and I hope I haven’t made the wrong decision.

You’re absolutely right and they will find something else to pick on her for. It’s an inflatables place.

My youngest son is a bit shorter than average. I made him use the booster seat, especially if it was a long journey including motorways. I just used to tell him "it's the law, nothing I can do mate." Nothing is more important than his safety.

There are loads of things I do to make him feel better about his height. He's a great gymnast, footballer and distance runner. I always remind him that shorter compact builds are an advantage in many sports and disciplines, he has the edge on taller competitors - which is true. I point out all the amazing, tallented shorter men on tv. He's proud of his height now.

sittingonabeach · 06/12/2025 10:48

There are quite a few posters on here who I wouldn’t trust to drive my DC.

When your DC are old enough to drive will you tell them to ignore these rules

It’s not about being a baby. It’s about being safe. Europe has car seats until 150cm for good reason.

This is a hill I’d die on - seat belts don’t fit well until about 150cm. If it was a local trip then perhaps. But not distance.

What happens if you never get to 150cms - so you have to use a booster forever?

I hope none of them have a height restriction 🙈
We went to a trampoline park and all the way there my DD sulked as she had looked it up online that they had an obstacle course but you had to be something like 130cm (which she isn't). She made such a fuss about how she wouldn't enjoy it. Thankfully when we got there they had changed it to 120cm and it was an old video she had seen.
I hope she does have a good day though and there isn't anything that causes an issue

Yabvu sorry girl

Edit, seen your updates, glad you let her go without it

Not sure what she said to you, but being seen as a baby and made fun of is a big deal at that age xx

Edited

Ignoring the law and ending up with a life changing injury, or worse is a pretty big deal at any age.

Exactly, in the UK you can age out at 12. I imagine most of Europe is the same.

Actually that would be another daft senario 130cm kid ages out at 12yo, taller younger sibling still needs a car seat at 140cm!

Mumsntfan1 · 06/12/2025 10:59

ShesTheAlbatross · 06/12/2025 09:46

Yes sorry. Mine are younger so I don’t know which one of those is likely to come first for a child. Do most children reach 36kg before 150cm?

ETA - I think the 36kg is in Ireland but not in all countries that have 150cm as the limit. In Germany it’s just the height.

Edited

Germany is 150cm or 12 years old. Whichever comes first.

Espressosummer · 06/12/2025 10:59

Namechangedforthis25 · 06/12/2025 10:36

Absolutely this!

1cm under. Well is it the same for 3cm?

there are boundaries, rules, limits for a reason

people haven’t plucked this stuff out of thin air - especially with car safety!

But a booster seat adds about 10 cm of height when a child is sitting on it. What is the difference that happens between 134cm and 135cm that means 134cm needs that 10cm of height and 135cm doesn't?

This law also doesn't account for body proportions. It's meant to be about where the seat belt sits but if a child has very long legs they can be above 135cm and still have the seatbelt dig into their neck whereas a child with a long torso could be 130cm and not have the seatbelt dig in.

Thank you! I have spoken to the school and these girls deny it so school close the case as no evidence! The other battle I have (and 100% sticking to incase anyone else decides to call me a rigid, embarrassing mum🤣) is tgat apparently the things she watches are for babies and she really should be watching squid games and stranger things!🤣 it’s so hard having girls!

Squid games no: stranger things fine 🙂

tbh though - if you’ve had to speak to school about these mean girls - why is she invited and why are you letting her go in the first place?

When it comes to children, you cant be rigid all the time. Its not like shes letting her go for a joyride on the bonnet

Well this is why it's important to understand the reasons behind the law, rather than just blindly (or loosely) following it. Safety wise, closer to 150cm is a seatbelt starts to fit properly.

TheNightingalesStarling · 06/12/2025 10:35

Its only 1cm under.
Its only half a pint over the limit.
That tyre is only 0.5mm under the limit
I was only going at 80mph
He's doing his test next week, he's fine
I'll pay my car insurance next week
The Mot will be fine for another month

They are all arbitrary laws really... but all are there for a reason!

yes but those examples are exaggerated. to continue your analogy to match with the actual difference in this instance (1cm!) it would be more like
"I only had a sip of a pint"
"I was only going at 71mph"

sittingonabeach · 06/12/2025 11:04

Isn't part of the car seat legislation also due to bone structure as well as height, weight etc, hence the age rule as well?

She invited because she’s grown up with one of the girls as the mum is my friend.

When she got the invite, I said it’s up to you but don’t forget how mean some of them have been and how they’ve made you feel. Have a think and let me know. She said she wanted to go so I said the same again and she kept saying she wants to go. Her dad sent me a barrage of texts blaming me saying I should tell her she can’t go, calling some of the kids fat little fuckers and all sorts!

I don’t think it’s my place to tell her she can’t go. She is 9, which I know is young, but how is she ever going to learn if I step in and refuse invites because some kids are awful. She has to navigate this through her own decisions. I can only advise and coach her as to what is a good and healthy friendship - and I spend a large proportion of time doing so. I just hope that she’ll realise as she develops.

Would dad be happy that you have broken law re car seat? Does he use booster seat with her?

andweallsingalong · 06/12/2025 11:21

StarDolphins · 06/12/2025 10:36

It’s not a wrap one, it’s just the square one that sits on the seat to lift her.

This.

The little square boosters are about as effective as a cushion from your lounge. If you want her to be safe she would need to be in a high back booster which wouldn't fit with so many in the car.

Which (and others) have been campaigning to "ban the booster" for years. They are just not safe

My 9 year old DD is only 126cm tall and she has a booster seat. On a five minute local journey, fine but on a one hour trip using major roads, no way.

Accidents can happen even if only a five minute local trip, so need to use one every time if she needs one

Okay - her dad aside (😳 that’s a different thing to unpick)

I think perhaps I would have said “you can’t go we have plans” and done something completely different with her today just to make her think that. Yes deceptive but keep her away from the mean girls but also gives her the get out clause cos you said no

I get where she’s coming from - she’s constantly trying to fit in and she’s hoping each contact allows her to do that.

can I ask is the friends daughter one of the bullies or is it her friends?
