Considering moving to Dehradun for Child sake

Hi all, we are seriously considering moving to Dehradun this year as my daughter is hyper allergic and is having health issues in Mumbai. We have some conerns and I am hoping you people will help me with answers. 1. Is it safe for me and my daughter to be there as my husband works out of city and will not be able to have an immediate switch 2. Which are good day schools considering fees structure, teaching pattern, teacher: student ratio, co-curricular activities etc 3. Which are good locations to live considering safety, access to daily need things, schools , extra classes for kids 4. Are there job opportunities for non teach roles, as we will be moving for a considerable period of time so might need to switch in a few years 5. Since we are moving to have better air and life style quality, is it a viable option for us? Any suggestions and advice is welcome .
