Should we be doing stuff or nothing

Hello all

I have posted on here before but I am finding it all really difficult. Our daughter is seven, she has SPD and ASD. She has been diagnosed for almost two years and the diagnosis' were given separately so do we treat them separately? We understand that our daughter comes as a whole and her diagnosis' make her who she is but do we get through each day treating her normally and allowing her to think things she does is ok? Do we do her spd therapy daily? How do we know when to do it?

I research information but I can't make it make sense.
