I don't know, maybe. Didn't seem like it though as she never mentioned trying anything else or even said if she'd been trying to wean for a long time, and she also seemed fairly proud of how quickly it made the child wean.
Surely there are many other ways than deceiving your child like that, and if she now thinks boobies are yucky, what issues is that going to cause in later life, or even how is it going to affect her possibly feeding her own children?
Just doesn't sit well with me at all..
