I too agree that these feelings come in waves. I get days when I question myself and whether I should keep on doing this, and then others where I am more content. Its a hard job. Physically and mentally demanding. Just hang in there and take it easy on yourself. Not every day needs to be perfect. Simplify things for yourself for a bit and revamp it once you feel your energy or drive back. As long as munchkins are safe and well fed and happy playing with each other then its a good day. You don't have to teach them everything. That's what preschool and kindergarten are for. I try to sometimes give myself that reminder and perspective; that I am a dayhome, not a preschool. Though my perfectionist self gets the best of me as well.
