I am obsessed with my kids attending school. My DS12 has never missed a day of school. We have taken red eye flights home and went straight from airport to school. I hope my DD7 follows in his footsteps. I feel it is important to kids to send the message that school is important and atendance is expected. The schools in our district have various holidays throughout the year, long weekends etc. that will allow for a vacation other than the standard summer vacations. Everyone is different though and you got to do what feels right for you.
