As a request from one of my readers, I'm writing my next story from a first person POV. The problem I have is that the main character is 5 years old. My understanding of people of that age is that they have a limited understanding of past and present tenses, and they would flip back and forth between the two when telling a story. When an adult does that, it's seen as unprofessional. Should I try to write it with little regard for keeping the tense consistent, or would it feel more authentic to have it change every now and then? For example: The noise was very loud. I looked all around, but I didn't find a lion or a tiger or even a cheater. Then I looked again; it was Mummy snoring! I had to cover my mouth to stop laughing, but nobody woke up so I tip-toed to the top of the stairs. I checked the time on John's phone; 11:52. It won't be long 'til Santa gets here! When Mummy snores, I go down two steps. She's so loud, nobody can hear the stairs creaking under my feet. Now I know the vocabulary is quite narrow and some of the words are wrong (I've used "cheater" instead of "cheetah"), but would it be accepted as a child's POV or simply disregarded as bad writing?
