B.S.
Was your baby early?? Do you feel any tenderness in your breast or any kind of leaking when he/she cries??(Your baby's cries should let your milk down)
Do you have implants or ever had breast surgery? Does your baby latch on? Talk to your Dr. as soon as you can!
I would recommend to keep trying to breastfeed and pump, keep stimulating the breast as much as you can and try drinking herbal tea & Beer helps to let the milk down.. They have teas called "Mother's Milk" to increase production.
Also, try not to stress about it, it will defeat your efforts.(this too is where Beer helps!) My LC recommended this to me at the hospital!!
Keep trying! It's too early to give up! Breastmilk is THE BEST gift you can give your baby!!! I BF all 3 of mine, it is also the most convenient way!!
See if you can get a lactation consultant to come to you.
I'm assuming that your baby is on formula, so always try to BF before you give a bottle.
Good luck!!!
