Dear Gretchen Leigh: Thank you very much for your query. I regret though I don’t think I’d be the best match. I have found parenting titles to be tricky to place and I need to have great confidence to move forward with a title in this very competitive category. I hope another agent feels differently and I wish you the best of luck.
[after receiving this first rejection, I adjusted the wording of my query letter to reflect the fact that it's not a self-help book by a parenting expert; more like comic relief for parents who are too hard on themselves]
