Hi, Deborah, I think it would depend on the age group you are aiming your story at eg baby books can just be a words or a few words with an illustration. Perhaps it would help to read other childrens books that are similar to what you have written. Might help.
Hello Deborah, there are some links you should go through.

Publishers websites often have guidelines, but generally there seems to be a maximum of 1000 words & preferably less.
