About the ND three years behind thing, our experience is the same. In fact, her reception teacher picked up on the fact that DD was emotionally less mature. But at the same time academically ahead. They can be a conundrum!
@SuperTrooper1111 , your DD not being bothered to join her friends and their boyfriends at the festival sounds just like DD. In fact, she said today that she can't ever see herself having a BF/GF. She's just not in that phase yet. I just want to make sure she doesn't rush into something she's not ready for just because others are.
@DataColour , what you said about your DS being a high achiever in the past but not so much now really resonated. DD is similar and she said more than once in year 8 that she'd 'become stupid' and she had no chance of passing her GCSES. She was desperately sad.
Loss of skills and regression is also a thing with ND, especially in times of stress or worry.
Frankly, I'm still trying to adapt to the idea that DD likely won't have the brilliant academic future she was predicted. At least not at the same time as everyone else, and then it may be too late. It's a very strange type of bereavement almost.
So what if they need more parental support for a bit longer? I'm often made to feel like I baby her and it gets on my bloody nerves! Nothing further from reality. In many ways, she's far more independent and mature than her peers, but she needs a hand with other things.
