Have felt that with the last two I sent off to school. In both cases I did not feel they were ready and started to doubt myself as in did I do enough to get them ready or was it "my fault". Nothing like giving yourself a guilt trip because a child can't draw a triangle, use scissors correctly, count past 7 despite three years of trying to teach them. Gotta remember the other 20 kids over the years that did go off to school ready.
