my kids are growing up so fast

I cant believe my oldest starts middle school this year. He is a grade ahead of where he normally would be for his age cause he wont be 11 until October but its still crazy. In 2 weeks when school starts back ill have a 6th grade, 3rd grader, 2nd grader, kindergartener and 2 first year of preschoolers. Its also crazy knowing all 6 of my kids will be in school this year.
