Detailed Answer:
Thanks for asking on HealthcareMagic.
I have gone carefully through your query and understand your concerns. It seems that your daughters have somehow contracted an infection, possibly viral in origin. The eye infection needs to be checked and it would be a good idea to visit the hospital. Depending on the findings the doctor may prescribe antibiotic drops like Ciprofloxacin. If the children are otherwise active you need not worry but if the activity level is lower and they seem lethargic, they would need medical attention anyway. Till then Dolo Drops (paracetamol) is right to be given.
Let me know if I could help further.
