I have had committed a series of mommy errors and this is by far one of the worst

So LO (13 months) has an ear infection that didn't clear up after a first administration of antibiotics 2 weeks ago. Dr gave us a second /different one. Today is the 2nd day of the 10-day course. When I was getting the dose I realized the bottle says it needs to be refrigerated.

I did not do that for the past 2 days.

Frantic, I called the pharmacist and they said it does compromise the effectiveness of the drug and I should call in for a new prescription. So I did (which I won't be able to get it until tomorrow morning).

I can not stop blaming myself what a horrible mother I am. How could I miss that? How could I? And I wonder if that was the reason why his infection didn't clear up in the first place because the previous prescription might need to be refrigerated too (I don't know now because I threw away the bottle). Then of course, I am so angry how come it doesn't write our clearly on the bottle while it was in small print on the side? Both the doctor and the pharmacist never said anything about refrigerating the meds. OK. I know. It is my fault at the end.

What is one of your mommy-error that you can not forgive yourself / feel that you need a confession?
