First of all, give yourself a break and slow down. Are you trying to be SuperMom & SuperDaycarelady and SuperWife, and on and on and on? That's my first guess. I kind of burn out once in a while too and I feel like I can't give my daycare 100%, but then I get my second wind.
The last few years I have decided to take a vacation week every 3 months. One week about March, one week in the summer, one week in Oct. and then Christmas comes with a few holidays even though it is hectic. It keeps me fresh and rested regularly and it's working great for me.
In my first few years as a daycare provider I was trying to pack the days with so many things but I realized that the children need time to play, just play. They are still learning and I'm still keeping them safe and giving them ideas and monitoring any problems. So I can sit back with a cup of tea and take a little break in the middle of the chaos. I deserve it and so do you because we worked damned LONG DAYS!
