Concern Mom😢

My baby girl left eye tear duct is still close. The doctor says it will open within her first year so don’t worry about it. But it has became infected where she needed eye drops but to me it’s making it worse now her eye is red everyday. I feel so bad because I don’t know if it’s bothering her or is it just me. We go back to the doctor Thursday I hope she has some answers for me. 😢😢😢😢
