Hi, I have15 days old twins. When they were first born they were admitted to the NICU for being underweight. Initially I said only allow breast milk but was not able to produce enough so they mixed breast milk and formula in a bottle and fed it to them. Now my twins are home and I have enough milk to go around. They latch on with no problem but after 10 minutes they seem to lose interest in the breast so we feed them breast milk through a bottle. Anyone have any...
