I store my pujmped milk into the Lansinoh bags as well as the playtex drop-ins. I have found that 8 out of 10 of the Lansinoh bagged milk is spoiled....it smells like vomit and tastes like vomit. But this does not happen with the drop-ins.
Has anyone else had this problem? They are not leaking and I use the bags directly after pumping, so there is no temp flucuations.
