She [the Head] told us it was more for emotional reasons as she would currently not be able to cope with the transition as she needs TLC
The school is still harping on about emotional stuff related to DD but to be honest I don’t see any of that
I don't wish to be confrontational, but up until you started this thread, you'd not seen any of your daughter's other needs either.
Please stop trying to bulldoze in and think you can fix everything with a few assessments and a few interventions. yes, they will help but whatever conditions your dd has, they won't go away whilst you try to steamroller them out of existence.
She has had 6 years of struggling at school without any support, cut her some slack and read up on the effects of anxiety especially in children with dyslexia and whatever other conditions her assessments have flagged up.
DD needs a change and less namby pambying
This, above all else is really the wrong attitude to take for and with your dd. You will do her a tremendous amount of harm and cause her anxiety to rocket even more.
Lowering her anxiety level by working out what the triggers are for that is often the key to a much less-stressed child who can then be in a place to start to cope with the difficulties every day throws at them.
This is not something you can take on board and sort out yourself with no knowledge of what you are doing but a 'she should snap out of it' attitude. It takes time and it also takes TLC. She's your dd, you should be motivated to help her in an appropriate way, that means giving her what she needs as opposed to what you think is best.
Quite often, kids with this type of challenge are emotionally developed to around two thirds of their chronological age, please observe her behaviour and notice when you want to tell her she should grow up or she's too old to do something she wants to do.
Believe me, there are a huge amount of mums who knew their children were struggling at primary school yet their schools never raised any problems and refused to back the parents up if they asked for assessments because they didn't see anything.
Your dd's school are aware that she needs help, you've started well, but please be open to listening to other peoples' concerns.
You cannot 'cure' your daughter, you can't make her be exactly like everyone else, but you can provide interventions which will make her life a lot easier.
As she grows, her needs will change, please be aware of that and always be aware that when her behaviour is at its most exasperating, that's when she needs the most help, not criticism.
