A nipple shield should be put on properly so that your baby can latch deeply and drink well from your breast. ​If the latch is not correct, not enough milk will be removed from your breast, in which case your supply can decrease.
A nipple shield also can act as a barrier between you and your baby. This can affect milk supply because there is less stimulation between your baby and your breast. The more skin-to-skin contact you can offer your baby, the better.

As nipple shields are recommended for breast feeding mums with inverted nipples, I assume that means the milk still gets through

In my experience, nipple shields are used by breast feeding mums when they have inverted nipples. So of course babies can still access the milk they need

I always thought a nipple shield was for breastfeeding mums with inverted nipples. Based on this, I would assume the milk can get through. I have never used them but have a friend who has whilst breastfeeding

Baby can get enough milk. My midwife suggested them for me as my son wouldn’t latch on without them.

Yes definitely! I fed my first with nipple shields until about 3 months (I had an awful time breastfeeding to begin with and they were a life saver). She was well fed and got plenty of milk during this time. I think my supply was better than if I had not used them as it helped me to relax and enjoy feeding instead of being anxious. I stopped using them around 3 months and went on to feed her until 16 months. Good luck!

Yes, as long as the shield fits properly & seals to the breast. I used them for both my bubs

Yes! My third child was born 3 weeks early and had a few health problems for the first few weeks. I used a nipple shield and it was brilliant. Not only was I no longer in pain, he was able to feed well and thrived. I had no trouble getting him off it arfter quite a long time using it (despite what I’d been told) He is now a thriving 3 year old.
