How annoying is that. I expressed now and again for ds1 and never had a problem with it.
I had an ounce of milk that had been in the fridge for about 5 days that I had expressed for ds2 but we hadn't had to use it so I thought I would give it to ds1 for novelty factor (he is still nursing but has been asking for ages if I would pump some milk for him)
He took one sniff and declared it was horrible. When the worlds biggest milk addict says yuk then there is definitely something up!!
So I had a sniff and a taste and omg it was vile. Not like it was off, but with the soapy taste that people have described when there is too much lipase in the milk.
I know about scalding before storing, but what a PITA.
Has this happened to any of you before where milk has been ok for one baby, but not another?
