I have no idea why but my supply tanked over the 4-day weekend. DS seems to be eating less frequently, but still every 4 hours so I can't imagine that would effect it that much. I usually pump at 10am and get 7oz. Today I pumped and got 1.5!!! What is going on! I am not sick, I drink lots of water and everything else seems to be normal. DS still wakes twice at night to eat. I used to have an oversupply. What would cause a sudden drop like this? I am worried, I don't have a huge freezer stash, only enough for about a week.
