What is the solution? I used to find the same with DS and am finding the same again. DD is now 4 weeks old and has had now 4 bottles of expressed milk. She has cluster fed all afternoon and evening and is now not satisfied - pulling away from breast. I'm worried that I may have to start introducing formula if this were to happen again as she is currently screaming her heart out hungry as we are sterilizing the bottle. If it makes any difference she was a big baby and only lost 2 ozs of birth weight.
