My six year old girl is threatening to never go to school again because the homeowrk is "too boring" and that she only likes recess. The work isn't that much and it's nothing she has trouble grasping. I think she's just tired out at the end of the day. I let her have a break before she does it and it seems to help but now she won't go to bed at night, anxious about the following day's homework. Any suggestions on how to quell anxiety and/or approach this subject?
