DC with suspected SEN starting mainstream school tomorrow, hand hold please

[Nervosa]

DC has suspected (highly likely from my opinion) ASD and Adhd, pending an assessment which is taking forever. Non verbal and still in nappies until a few months ago, speech has come on well (single words, short phrases etc) but still way behind their peers. Has energy for days and cannot sit still.

Due to start reception tomorrow (a phased start to see how they settle in) and I'm full of so much anxiety. I don't know what I'm looking for really, a hand hold or reassurance from others who have been in the same position and their child has thrived?

This was interesting for me to read - my children are in their 20's now. It is interesting to see that mainstream schools take children at 4 who are non- verbal and or in nappies. I remember the instructions when my son started school we were told during preschool year that they would not be able to start school in reception unless they were toilet trained and had a reasonable vocabulary.
Unless they had a physical disability wheelchair bound etc. This applied to ND children as well as NT. They also had to be able to eat with a knife and fork if they were having school dinners! It seems times have changed a bit since the late 90's
