How do I help my super sensitive 7 year old become more resilient?

[PleaseJustEat]

My 7 year old DD is healthy and for the most part happy, but she is so very sensitive to any form of telling off, perceived criticism or things not going her way. She is in tears multiple times a day and has always been like this. Her teachers have said she cries more than average and is very sensitive to any kind of falling out or arguments in class, even when they don’t affect her personally. How on earth do I make her tougher? She does sports and competes. Very occasionally she will cry if she loses if she feels the game has been unfair, but generally she doesn’t cry in the normal course of play if she loses. It just seems to be in day to day life, she can’t cope. I’m worried it could lead to mental health issues when she is older. She is very much loved. She has a younger sibling who she can get quite jealous of but generally gets on well with (and who has the resilience of a rubber ball…nothing bothers her!).
Anyone any inspiration for how to help her toughen up?

Have the school said anything more than she's cries more than usual?

Have they suggested that SENCO hace a look at her? Just wondering as a heightened sense of injustice and sensitivity to criticism can, but not always, be signs of ASD in girls.

They just really reinforced the “she’s very sensitive” point…so when she gets her work wrong she often gets frustrated to the point she cries (and she’s pretty smart, top groups etc) and that she cries quite a bit in the playground eg if she falls she automatically bursts into tears whereas most other kids would get back up again and start playing.
she takes things very personally (why do things always go wrong for me <they don’t>) and when she is upset she says she is stupid (when she clearly is very bright).
They haven’t suggested senco and I feel like they are quite on the ball with that kind of thing (there are a few kids in her class with various additional needs). I’ll research ASD though - I’ve had no exposure to it before so don’t really know much about it. Thanks!

Definitely read up on ASD in girls specifically. It was our experience that if the DC behave well and get the grades, school and SENCO are less likely to be interested. It doesn't mean though that your DD shouldn't have support, should she need it. It sounds at the very least that they shotgun be offering something like Emotional Literacy Support. Have a look at the Zones of Regulation.

Our DD was pretty similar, the wheels really started to cone off when starting High School coincided with Puberty.

I'd also think about posting in the SN Children Section to see if any of the more experienced MNers think that she may need support too.
