my daughter is 6 years 10 months old and she is complaining about the left breast pain is it common or early puberty sing

A. It could also be associated with gas because if your child is six years old I don’t think so it could be associated with puberty because when puberty happens you can see growth in the breast you can see under arm hair and also vagina hair these are the sign of early puberty or when the child is about to hit puberty in any age so please check with your doctor once
