Coastal City with good hospital for kids nearby

Hello,
Could you advise on coastal city with good children's hospital  nearby. I am planning to stay about a month in  Dominican Republic.  Have 3 kids, and I want to make sure there is a good hospital nearby.
Basically,  I am looking for:

*Good hospital nearby
*Safe environment
*Grocery stores (Russian store is a plus)
*Kids playgrounds
*Plenty of Spanish speaking kids
*Nice Beach

Thank you

Kseniya

Welcome to the forums.   I don't know about kids hospitals in tourist areas so will defer to others here.
