Amoxicillin 15 month old

I took my daughter to the pediatrician for fevers and they diagnosed her with hand foot mouth and an ear infection. Hand, foot mouth is basically gone but she’s on day 4 of amoxicillin. No diarrhea or anything abnormal but reading through the internet doesn’t make me feel good about this antibiotic at such a young age. What is everyone’s thoughts on this and should I continue giving her the antibiotics. Thank you
