Good evening! I've been writing here since my daughter was born, thank you all for your feedback ? Today I'm worried because my little one got sick. It started with a runny nose, and today her voice is whistling and there's a cough too ??‍♀️ I called the pediatrician, she says "the lungs are clean, but if the cough gets worse on the weekend give her Ospomox" I don't know if I should give her an antibiotic or not. Should I put her in the hospital? My baby is only 2 months old. I'm so scared, they say that kids can get worse quickly, maybe ??‍♀️??‍♀️??‍♀️
