School Problems

Our five year old son started kindergarten this fall. He is a smart, shy, intense, persistent little boy. I was conflicted about whether to send him and am still struggling to figure out what is right for him. He is very difficult in the morning, refusing to get dressed, becoming very angry at times, and just repeatedly saying he doesn't like school. I volunteer in the classroom though and have met with the teacher repeatedly. He does great when he is there - he is engaged, seems happy, and is very capable of keeping up with his peers. He also seems happier when he comes home - he seems to feel good about his accomplishment, is more cooperative and more confident. I have considered homeschooling - but he has such a high need for novelty and social interaction, that it is difficult to keep him engaged and happy at home. Our personalities are very similar and our relationship also seems to benefit from having some space, as does his relationship with his little brother. We live in a smaller town, without many private school options. He has always been difficult to read, it is hard to take him at face value as he avoids anything new or difficult until he gets into the situation, then he seems to feel good about it, until he has to go back. I just really want to do what is best for him and am very weary of the morning battles. Thank you.
