Breast-feeding support
[This review was collected as part of a promotion.] There’s no more guessing of if your baby had enough milk or is actually getting milk with this product. It’s really a great idea. You can see the milk flowing. It’s nice and portable. Comes with a travel bag and comes in different sizes for your nipple shape overall pretty impressed with this product.

Easy to use
[This review was collected as part of a promotion.] Did not work for us. My baby ended up not liking the nipple shield but I didn’t have a huge issue with latch to start with, I was just experiencing a little soreness. The product itself is quality and durable, we just didn’t need it. Easy to use and easy to wash.

It works, just not the one for me
[This review was collected as part of a promotion.] I love the carrying case that can also be used to sterilize it and the syringe to help flush it clean. However, my baby wasn’t a fan of this shield. She got frustrated with it and how much work she had to do to get the milk compared to not having a shield. The plastic material of the shield wasn’t my favorite, it made my nipple feel sweaty. It does work though if you need something to protect your nipples as they adjust to breastfeeding.

Thumbs down graphic, would not recommend
14 March, 2026Verified purchase
good idea, not so good in practicality .
it doesn't work effectively. baby struggled to latch on it and have the milk come through. unfortunately you can't return... so it's just a waste of $30.

I’m very happy with this product.
[This review was collected as part of a promotion.] I’m very happy with this product. The Munchkin Flow Nipple Shied really helped make breastfeeding more comfortable. The sheilds are soft, thin, and almost unnoticeable, which makes its easy for the baby to latch and feed naturally, I especially like the transparent channel that allows you to see the milk flow and make sure the baby is feeding properly.

Great product when needed!
[This review was collected as part of a promotion.] I think this is a fantastic short term solution! I used this to help establish nursing, it gave me a lot of confidence knowing she was getting adequate amounts of milk! I also love that you can sterilize in the container! I wish the silicone was medical grade and I find the sizing slightly bigger than other nipples shields and a little bulkier. I wouldn’t use it long term as the cleaning is very intensive and I worry about milk being legs inside to grow bacteria. The case is nice and has everything you need to upkeep and travel with the product!

Good Product
[This review was collected as part of a promotion.] I love how it is packaged and the storage case is very handy. It is very comfy and not too complicated to put on. Easy to clean and appreciate the cleaning device included. This one fit the best of the 2 sizes.

Game changer
[This review was collected as part of a promotion.] This is a one of a kind product! I’ve used nipple shields in the past and didn’t think much of them. They can be extremely helpful in the first few days of nursing. These are a game changer for first time moms and experienced nursing mothers alike. All babies have different obstacles when learning to nurse and this product can really change that course. Being able to see the milk flow can really guide nursing sessions. It fits extremely well to prevent leaking and it’s so incredibly thin that it doesn’t cause nipple confusion. The case it comes in is really well made and the cleaning device is really great.

Nifty, but…
[This review was collected as part of a promotion.] This is a pretty cool device, BUT it states on the package it is “durable to last for up to 200 nursing sessions.” That may seem like a lot to some people, but in reality that’s only a maximum of 25 days! Starting out, you have to nurse 8 times a day! Now, having said that, it’s still pretty nifty. It’s soft, fits well, and has a cool milk viewing channel. It comes with a cleaning syringe. The case can double as a steamer for sterilizing and is microwave safe. The convenience and wow factor are there for sure.

Works great
[This review was collected as part of a promotion.] Great idea especially for first time mothers! I love that you can see when your let down happens because I couldn’t feel mine, and it gave me peace of mind. It comes In a nice case that doubles as a sterilizer and it’s easy to travel with and you can clean it easily with the syringe that comes with it, im usually a 19mm but the 20mm fits good! This also helped baby with latch and heavy flow

A must have for nursing moms!
[This review was collected as part of a promotion.] The Munchkin flow Nipple shield is thoughtfully designed to breastfeeding support. The see-through milk channel lets you easily watch milk flow that gives confidence and ease with very feeding session. The travel case doubles as a sterilizer making it super convinient for on the go use. It also includes a reusable cleaning syringe so keeping the shield clean is quick and easy. A practical well built accessory for nursing moms!

Light weight easy
[This review was collected as part of a promotion.] These are light weight and easy to use. They are portable. The flow feature is cool but it’s still unclear how much baby is swallowing and getting. So not sure it’s totally necessary but it’s a good feature/thought. Hard to get them to stick to your nipple and stay in place though. Baby can swat it off. My baby did not prefer it she knew it was there. She is 11 months though maybe a younger baby would be less aware.

Awesome!
[This review was collected as part of a promotion.] I should start by saying that I am an oversupplier and have had zero breastfeeding issues but I can see how these could be beneficial for the early stages where breastfeeding can be painful or even just someone curious about if the baby is actually getting anything

Comfy and easy to use
[This review was collected as part of a promotion.] This nipple shield works really well! It’s really nice that it can go over the nipple and is not super hard or bulky. It’s pretty comfortable excited that this is something that has been added to the Munchkin line.
