Hi there!
I am sure your baby is fine. It was an accident and please don't beat yourself up about it. You did what you could do by pumping ahead of time. I must say that if I was in your place, I would have ended up feeding my dd as well if she refused the bottle and cried for that long! Here is a bit of information that I found in regards to this issue. I would say that you didn't harm your baby.
La Leche League's THE BREASTFEEDING ANSWER BOOK (pp. 597-598) says:
Alcohol passes freely into mother's milk and has been found to peak about 30 to 60 minutes after consumption, 60 to 90 minutes when taken with food. Alcohol also freely passes out of a mother's milk and her system. It takes a 120 pound woman about two to three hours to eliminate from her body the alcohol in one serving of beer or wine...the more alcohol that is consumed, the longer it takes for it to be eliminated. It takes up to 13 hours for a 120 pound woman to eliminate the alcohol from one high-alcohol drink.
Thomas W. Hale, R.Ph. Ph.D., member of the LLLI Health Advisory Council, says this in his book Medications and Mothers' Milk (11th ed.):
Adult metabolism of alcohol is approximately 1 oz in 3 hours, so that mothers who ingest alcohol in moderate amounts can generally return to breastfeeding as soon as they feel neurologically normal.
Important Considerations
Your baby's age
A newborn has an immature liver, and will be more affected by alcohol
Up until around 3 months of age, infants metabolize alcohol at about half the rate of adults
An older baby can metabolize alcohol more quickly than a young infant
Your weight
A person's size has an impact on how quickly they metabolize alcohol
A heavier person can metabolize alcohol more quickly than a lighter person
Amount of alcohol
The effect of alcohol on the baby is directly related to the amount of alcohol that is consumed
The more alcohol consumed, the longer it takes to clear the mother's body
Will you be eating
An alcoholic drink consumed with food decreases absorbtion
Please don't be upset! I am certainly not a doctor, but I am sure your baby is just fine!
