Breast milk?

that's a good question.

I would think that it would be more about the frequency of the suction being applied also.
You need to stimulate the glands regularly, and consistently for your hormones to kick in and respond to the 'demand'

You may get a clear liquid, but this is not necessarily breast milk

heard that to

I'm a lactation consultant and my guess is that these wouldn't cause one to produce milk.

When a woman wants to induce lactation (for an adopted or foster baby) or relactate (after a premature weaning) she has a LOT of work to do; pumping with a hospital quality pump, every 2-3 hours round the clock, taking medications which raise her prolactin levels, putting the baby to the breast with a tube device to bring supplement to the baby while providing more actual infant stimulation to the breast itself... and even then sometimes it doesn't work.

Producing milk from using nipple sucker toys would be highly unlikely and I think that someone who could produce milk, without being pregnant or just having a baby JUST from using these probably would need to have her prolactin levels checked for a pituitary disorder or tumor. These won't produce enough stimulation in a non-lactating or pregnant woman to cause milk production.

However, as pregnant women have very high levels of certain hormones that ARE effected by nipple stimulation (because that's what's supposed to happen after the birth, nipple stimulation to make milk) that I would NOT use these during pregnancy.

I wouldn't worry about it.

Thanks for the heads up, Beck.

Absolutely not for me. I stopped nursing my daughter May 2011 and these have not caused any issues for me since I got them a couple weeks ago.

Well. I didn't get these, but the little suckers, and I'd have to say from surprising personal experience yes. I have breast fed before, but my youngest is 7, so it's been over 6 years.
