Ok, Miss Anonymous, I have been writing a children's book for the last 10 years. Picking it up and putting it down. Reason being is because I traveled a lot and really found it hard to focus. Dedicated to my Grandfather who was a writer in his hay day. He became ill and 2 days before my flight to see him, he pasted.I don't want to be mean about this, but my first piece of advice to you is to carefully proofread anything you send to an editor. Your second sentence was a fragment, but I was going to let that slide as possibly stylistic. But your third sentence is ungrammatical / repetitious: "reason being is because". Your fourth sentence is a fragment, too. And you mean passed not pasted. That kind of trouble with the past tense raises an editor's eyebrows.
He knew I had the book written and knew what it was about but I was going to read it to him myself. Anyway. I went to a convention when I came back home. Spoke to agents, publishers, and editors. My picture book is to long.Too, not to.
And with the grief i couldn't pick it up to chop the extras. I have a friend who is a pretty well known author of adult books. Also contacts inside Random House. But I have no real help.. I need to get this beautiful book on the shelf for the children and for my grandmother. It really is a good book. I know every says that but i promise, who ever has read it, has loved it. So where to now? I looked up fees for an editor and it was an outrage amount per page. Its been edited by a college professor as a favor but not edited by a children's book editor. So its not bad, its just to long. I'm in no man land. Its really a good book.Everyone, not every. Whoever is one word. Outrageous, not outrage. It's, not its. No man's land not no man land. Etc.
Ok, now for the advice you asked for:
Join the SCBWI and find a critique group. Ask them where/how they would recommend cutting the text down.
And a bit more advice you didn't ask for:
I sympathize about your loss. However: You do not need to get this published for your grandmother. She can read it just fine right now.
Also, take my advice and do not mention your grandparents as any kind of motive when you submit this to editors and agents: we've all seen many, many submissions whose main reason for being was someone who was dead, or dying, or sick, or some other misfortune that meant the submitter HAD to get THIS manuscript published SOON in that person's memory/to ease that person's pain. Those submissions have been uniformly not for anyone else. We have to be able to sell a book to a LOT of people, remember?
Do not be surprised if the people at the SCBWI suggest you should try writing something else: part of becoming a good writer for children is practicing, and practicing some more.
If you want to be a good writer for children, welcome to the industry. It's a lot of work.
But if the only thing you care about is this one manuscript, then I doubt the work it will take will be worth it to you.
