Anyone tried breastmilk bath on your LO? Please share on how much BM u used for each bath and how? TIA!

One of my friends did. She had frozen some of her breast milk in ice cube trays so she used those. She naturally defrosted a few in a bowl till room temperature and used a wash cloth to wipe baby off. After that, she rinsed baby off as per normal in his bath. Don't think she did it regularly, her breast milk is wayyy too precious to be used as bath water daily.
