There is nothing wrong with looking at your life and your priorities, and realizing that something has to give.
Do your family/kids help with them at all, or do you do everything? I combine family/kid time with cleaning time after dinner, my daughter holds the snakes while I clean the tubs.
Also, you have seven listed... are they in a rack or do you house them in tanks? Tanks take a lot more time for maintenance, where I have 22 BP's now spread over three racks, and can keep them cleaned and watered each day with just a few minutes work.
