Hi. I am planning to take a CPR course that is 16 hrs long, one day for 9 hrs. My baby is almost 5 months old ( one more week) and I plan to pump for bottles, but don't know how much breast milk to put in the bottles as I normally fed from the breast. Any suggestions?? I know formula fed babies get 7-8 ounces per feeding, but I have not a clue how much breast milk to put in the bottles. Also, I am worried it will effect my milk supply if I am not able to pump during this event... should I be worried? Thanks for any suggestions.
