the difference, guess is polyclinic every visit different doctors.. and pediatrician is standard the doctor you want. service different too!
pediatrician would be better =) to me, i find that polyclinic very rude sometimes and really long waiting hours!! the price difference by alot.
i brought my girl to pediatrician for her jab.. total package cost about $450. and polyclinic total is about $300+ only? around there.. not very sure.
hope it helps
