K.O.
I think you have to suck it up. It's normal. Other teams are practicing before you. Some parents are the 5 oclock time are thinking "how am i going to make it to practice from work at that time?" The 6 o'clock parents are thinking "this is an awful practice time. It's right in the middle of dinner." There may even be an 8 o'clock practice time.
my kids to go bed at 7:30 and there are nights with baseball that the game doesn't start until 7:30 so the game isn't over untiil 9:00. My husband travels, so that means 4 young kids all out WAY past their bedtime. It's a casuality of organized team sports.
