our son was due to lack of breast milk on my part already in the hospital after birth exactly these milk - she has well tolerated. have in the meantime a more favorable / other HA -Pre milk bought 1 x for a price in the drugstore. While he has tolerated these other milk, but she was not so readily soluble, looked greasy (although the nutritional information in almost all areas were almost or totally identical between BEBA and billiigeren formulas). In the bottle always stayed at the cheaper version greasy fat residues inside the bottle rim shake and stir thoroughly -despite + my son had rarely / irregular bowel movements with it. Bin then (.. Only 1 Pack billiigerer Anfangsnahr) switched to BEBA back -> defecation has again works regularly. Ie in the case it is worthwhile to spend a little more, also not part of the BEBA formulas so at the very expensive products + was slightly more favorable than at the drugstore for a single package in bulk containers at Amazon.
