My policy is 60 days notice to the 'contract' so changes to the hours would fall under that category ... I agree with the other ladies it is a very small change and hopefully everyone can accomodate that change ~ I made the same change a few years back only my hours are now 7:30 - 4:30 with an additional charge for care between 7-7:30am or 4:30-5pm and amazingly all my clients who use to send their kids here until after 5 were able to suddenly be here by 4:30 when it was going to cost them 'extra' to use such a long day so they obviously did not NEED that long a day it was just 'easier' to leave their children here that long rather than arrange shorter days between one parent dropping off and another picking up to stay within 9 hours
