If any of you mommy's have a breastfed baby that refuses a bottle try the Nuk Simply Natural bottles. My daughter would cry and scream and take less than half an oz whenever my mom tried to feed her. A friend told me about this bottle and she just drank 3 oz no problem. I'm so excited I can be gone more than 2 hours. I felt horrible for leaving her for very long cus she would refuse her bottle and just cry and scream for my mom.
