Breast milk baths???

I'm 4m pp and I had stopped breast feeding at 1 month. (Okay this is going to sound a bit silly now....) I have 1 8oz bag of breast milk that I was saving in the freezer just because I'm planning on not having anymore kids....therefore I'll never have breast milk again.....well....I was feeling very sad and emotional with pp hormones lol and I couldn't get rid of it and wanted to keep it forever!!! Lol

Any who....I'm over most of my pp emotional roller coaster thing and I was looking up all the other uses for breast milk and came across breast milk baths for babies..... Just mixing it in the water.

I thought maybe we could do that to have a "special thing" sorta thing

Lol as opposed to it just sitting there or being thrown away.

Has anyone done or heard of this?

( if it wasn't already in there for 4 months I would make the teething cubes or popicles....but my lo isn't teething yet....and I just don't want to keep it that long for my baby )
