Has anyone had an experience of white granules and/or  residue being on their baby’s skin after urination?  I thought perhaps this was from the diaper but after a blood draw on my daughter this morning and quite a bit of crying, there was the same white residue where she cried.  Is this perhaps salt being lost?  She is a 5 month old SW and this is my first child so I thought I would ask.

Thanks beforehand,

Rebecca
