DD aged 5 (ASD) is in a double class anyway...unfortunatley they decided to combine two classes this year...two teachers and 50+ DCs as of this week in one big room. :( They spoke about it all last week in class but DD is not happy and already finds school hard work. As a girl with ASD she tends to grin and bear it but comes home very anxious, exhausted, face picks and has nightmares. :( Her teacher always says she is 'fine'in school 'all DCs get tired' and 'DD has differerent behaviours at home'. 
As she is now 5 Early Years Inclusion have left the scene, we are waiting for Autism Team this month.
The SENCO avoids me and is a bit of a nodding dog...but no action...still waiting for IEP review to be rescheduled after the snow delayed us, no support as recommended by SALT in OCTOBER!
This weekend DD was very upset at noises she could normally tollerate, we had her ear defenders on outside. We normally only use them for in the night fireworks or loud wind...weather fear! So now I am worried about today....and the rest of term.
...BTW we are visiting a new school with more SN experience tomorrow...fingers crossed ...even if we have to move house.
I feel better for that rant. Anyone got similar worries as it is January so many new DCs in school.
