I need some help in explaining the following to my DS who is NT and hope you may be able to help me.
I live in a street where we have a lot of children from 3 year olds upto 8/9 year olds. They all play together and have done for a good few years now.
In this group we have a friend who has two DSs the eldest is NT and the youngest has SN. He is 4yo but he has the mental age of a 2 1/2yo. He has just started attending the local school with all the other children.
I have two DSs 6yo and 3yo and my DS1 has started asking me questions about my friends DS2, I will call him J.
A bit more background information is that during the end of last year and this summer they have spent a lot of time together and whilst my DS2 has moved on and grown up iykwim J has not, he has stayed the same. My DS1 has noticed this and has started to ask me questions i.e "Does J have his own sign language" and "why is J different"?
I have spoken to my friend about all this and she suggested just telling my DS2 that J is slower than everybody else
I don't feel that is the right thing to say but I am struggling to find the correct terms/words to use.
I don't understand enough about SN and the terms/words I knew as a child (I am 40) have changed so much.
Thank you for reading this far and I hope you can help with such a silly request
