Is the above OK (to mix formula and MBM in same bottle or container ahead of time and then portion out some into a bottle for each feed?
I'm asking because my lo is 7weeks old, and has seemed much grassier and fussier lately, and today I did this and noticed that it tasted bitter, almost like soap. I threw everything away worried that it was rotten/contaminated/off. But that was a waste if precious MBM and I was upset about that.
Also, as we are on the go a lot, can formula be left in my bag for a trip to the doctors or to shopping without a cooler/ice pack? If so, for how long?
