I totally screwed myself over with my sibling discount. My spots are $35/day and I gave a family with twins a rate of $50/day. I have had to terminate them now due to horrendous behaviours and now have 2 open spots...plus now that I think of all the money I technically lost per day/week/month its crazy. My new sibling rate will only be $5 off the regular rate for the second child. First child will pay full fee.
