Raising the cuteness factor of my children's picture book

Looked through my book today and was impressed by the lack of consistency in how I draw my characters. My original concept was to make everyone about 12-years old. Unfortunately, I didn’t stick to the plan. On one page Betty is 10-years old, and on the next she’s 25. This is problem with all of the characters. The big question is, will I redraw the entire book? Or will I wearily publish an amateurish shambles?

Time will tell.
