My DS is 4, he has a stammer and is under the SALT. We have to do one to one time every day with him to encourage fluent speech. We have an older & younger DD (7 & 1).
He is an august birthday and just started school in sept. We have gone against the grain for the school and opted to keep him part time, with 1 full day a week.(which we have just increased to 2). This is to allow him some quiet space at home to effectively carry out his speech therapy.
His teacher at parents eve has said that he is massively missing out on his education, because they do their numeracy in the afternoon (he does mornings), and he will have huge gaps in his knowledge when he enters year 1.
I feel really angry that she is so unsupportive, he will be full time when he is legally required to be (after easter) but until then, rather than offer help and give us the curriculum he is missing out on, or changing his numeracy to the mornings, she has written him off.
Its not like we keep him at home to go shopping!
What to do??????? 
I want to have a meeting and discuss it further but I also feel she is SO against him being part time, that it wont be that productive.
