I pump for my baby who is 5 mo now when at work everyday Monday thru friday. I have been doing this since i joined work 3 months ago. Till yesterday morning I was getting 4-5 oz total each time i pumped. I pumped for 3 times when away from my baby and fed him before leaving and after returning. All of a sudden when I pumped yesterday morning at work i got normal output but since afternoon i have not been getting any let down which leads to hardly 1 oz in total which i hand expressed both times. I went home fed my baby and all was fine. i thought it was just one off day. but today morning at work its the same. No let down... I come to know when let down occurs and i get milk while i pump. i dont have too much in freezer so i need to rectify this issue asap. i dont wont to get to formula. can anyone help. what may be wrong.. plz help!!
