The geo-location is very important when you have a question related to the child. This ensures that it is a nearby community of parents, who can support each other by giving a more precise/relevant answer because in 25 miles radius parents will have the same toy stores, pediatricians, schools, apparel stores, weather conditions and much more. Geo-location based system will also help parents filter and analyse majority of the questions.
When a question is asked, each question will have multiple answers from different parents. A father/mother knows the best answer for the child and hence will be able to choose any answer, rate the answer and will be able to open message stream.
