While I don’t doubt she uses a SNS sometimes, I think a lot of her baby at breast is dry nursing: https://www.mamamia.com.au/dry-nursing/

I did this with my ex girlfriend’s baby when we were together. I took meds to bring in milk but o could never pump more than a couple ounces all day. I tried the SNS but my girlfriend’s milk had an enzyme that made any expressed milk quickly change to a soapy flavor.

We both “nursed” the baby until she was 2. It made it easier to soothe her for naps and when she was fussy.

I don’t have an issue with the babies at the breast. I do, however, take issue with her “supply”. However, if she admitted to not lactating that could lead to why she wasn’t actually pregnant.
