I would love a class to take dd1 to.
She used to do tumbletots, and loved it, but as she got older and the gulf between her and her classmates got bigger, she was unable to continue.
I would say that the main things i would look out for would be:
acceptance that dd1 will not understand instructions straight away
acceptance that even if she does, she may not comply.
understanding that, just because dd1 is unable to understand/talk well, her physical skills are not necessarily the same as those of children much younger than her (we had this problem at tumbletots. dd1 needed to move up the classes to keep her challenged by the climbing, but she was unable to comprehend the stricter routines of the higher classes, and did not want to sit still for 10 mintues at the beginning telling everyone her news - she saw that as wasted climbing time! )
I am not sure that I would prefer a class that only caters for children with LDs, as dd1 is able to, in part, access mainstream activities as long as there is awareness that she is disabled (autisitc, so not always obvious).
It is a fine balance for me. If strict (and I mean this in the loosest sense, more an idea of structure to stave off chaos) rules are in place, then dd1 can not cope (eg she may want to continue with just one activity rather than move around different skills). However, if there are no rules about changing areas/waiting for another go etc then dd1 takes full advantage of this and chaos follows.
to be honest, i would be looking for a class that dd1 could attend where she did not necessarily have to comply with any routines, as she might not be able to, but where there was an expectation tht she would try to.
So, for example, to go back to tumbletots, dd1 was fine in the toddler class, where te equipment was set up, and parents went around, supposedly in a set order, bt no one really minded if the toddlers set their own agenda (obv no barging in, and waiting as nicely as a 2 year old can for their turn etc, but could spend the whole class doing one piece of equipment if that is what was wanted).
but, when she moved up to the next class, she was supposed to move around between 3 areas in a train formation when someone else told her to. So she got 10 mins to explore a group of maybe 3-4 different challenges (climbing, balancing, swinging) then, just as she was getting into her stride, she had to move on to the next group. It would have been better for her if she could have been outside the groups, going on each set of equipment as it suited her (again, with no barging in etc, she can wait quite nicely if she puts her mind to it). the problem she had was with the social set up - dividing the class into groups who were then told what to do.
the reason I was given for her not being allowed to do this was that they were preparing the children for the next class up where parents drop off and leave the children to it, so dd1 needed to be able to listen to the leaders. I can see their point, and agree that dd1 needs to listen to the leaders, but tbh, she is not going to be able to be dropped off for a very long time. I do see that to have one rule for one child, and another for the res tof the class at 4 years old is tricky though.
