Adding milk to melt and pour?

[KiwiMoose]

I recently made (at the request of a local midwife) a batch of cold processed soap using her breast milk as the water content. She totally loved it and promoted it on her midwives fb group page and was inundated ( as was I) with requests for the same from many new mums all over the country. She immediately saw a niche, and started making up DIY packs to send out. She has been doing a roaring trade from what i can see on insagram - packaging up a silicone mold, 500g of M&P soap base and instructions on how to make their own soap by adding 150g of their own breast milk to the soap base.
Is it just me, or is this a total no-no? Won't the milk go off within a couple of weeks? It's not like cold processed soap where the milk is essentially preserved by the lye in the saponification process is it?
I don't know whether I should tell her, not tell her, or something else??
Has anyone ever used milk in M&P and how long did it last before it went stinky?

I've never used milk in M&P and it seems like a very bad idea. Especially at 150g milk:500g soap base - that seems like a lot of liquid to add and I wonder if the soap would even set up. I would tell her - here is a link to an article Purées & Fresh Ingredients in Melt and Pour Soap - Soap Queen

It's not just you. Milk and other fresh ingredients WILL go bad.

I would absolutely warn her before the complaints start rolling in or she gets sued because someone gets sick.

The baby will be washed - so they will smell like off breast milk.

Tell her they will be washing with "Spoiled" milk.

A tablespoon of milk probably wouldn’t hurt but I agree 150 g is going to get stinky.

You must not have had babies and lost a bottle.

I think any amount of milk will spoil and stink.
