If two days, or a week, make a great big difference in class, then the teacher is doing something wrong. Look at the end of the year or holiday weeks, basically, the kids do nothing, play games and hang out, just to make the 180 days (or whatever ini your area). As long as the child has a relatively good record of school days, what's the problem. There ARE other things in the world besides school, like experiencing time with the family and having a life. If your child is doing well in school then i thing the teacher overstepped her bounds in saddling your child with all her "pros" and "cons". the biggest pro is time with her family and life experiences.
Take is from someone whose 12 year old was killed in an accident 5 months after we went on a disney vacation, there is not one minute of the day that i regret taking her out of school for a vacation with the two of us. Again, frankly, had i not taken the time to have that extra special vacation with her, i think i would have killed myself. Life can be tragically short, don't let someone else decide what kind of life you give your child. My daughter's principal asked if he could go with us, two of her teachers had a problem with taking her out of school for a week - too bad. You never know is my motto, and I thank God that i took her out of school for that week, we had the time of our lives and it couldn't have been more fun.
i am taking my 5 year old and my 3 year old out of school this december to go to disney and i will be d*&^%$ if i will let someone else tell my or my child what they need to decide.

Family comes first, and if the school or teacher is not happy with that, too bad.
