DD is almost 6 months old and I got a cold over the weekend. I've noticed already today that my supply is down a little bit, as I haven't been able to pump as much as I normally get. I have a sore throat, runny/stuffy nose and just overall feel tired. Can I take any medicine? What can I do to encourage my supply back up? I'm supposed to be in all-day meetings this week for work, so I need to get feeling better asap!
