The pressure put on children

Its Monday, and already Thomas is tired for the new week at school, he had a busy weekend, rushing off to cubs outing, then homework and reading, i just feel that they work the children too hard, at nine years old, reading every night, which in my view takes the enjoyment out of it, homework (maths) twice a week and spellings home work, poor lamb is exhausted by Thursday x!! life isn't about studying all the time surely, where's the fun ? i try to make weekends as chilled as possible but i am starting to feel the pressure of not doing enough with him.!!
