Female/Child Vocalist for singing Rhymes

Hi I can provide you the child's voice over by a child who has perfect English and a very singsong voice. What should be the age of the child? I can send you a sample audio if you wish.

Listen to my voice and you won’t go for any other choice

I'm an experienced voice artist, fluent in English. I hold a Bachelor's degree in English and work experience in USA, therefore I can be the perfect voice artist for your project. Relevant Skills and Experience I have experience in recording. Please don't hesitate to contact me. Thank you
