MAM Sealing Discs Pack of 3, Baby Bottle Sealing Discs for Hygienic Breast Milk Storage, Suitable for MAM Bottles and Trainer Bottles, Newborn Essentials

I mean seriously, how difficult can it be to properly use this? There are so many negative reviews on here, including one of the top reviews with a video showing the user incorrectly using it. Of course it is destined to leak if you do not use it properly.To summarise, pop this in place of where the teat would usually go through the twistable cap, twist and seal, shake = no leaks. It's as simple as that!I'm in shock at the lack of common sense from other users having difficulties with this. It's really not that difficult to understand nor requires adequate brain capacity to properly use.Overall, works incredibly well with absolutely no leaks whatsoever. Saves shaking normally with teat on that would usually expand the vent and leak everywhere. Very confident in this and will continue using it for each formula feed.

These fit the mam bottles to allow them to be made up and stored in the fridge with milk. I used them to make up bottles of expressed breast milk for later and they work well. You just have to remember to take them out before you use it for the next feed.

Once upon a time these were supplied in the bottle kits but it seems not now , they're a lifesaver when travelling so always good to have A*****

Easy to use stops Bottles from leaking in your bag, how ever a little bit pricey for just two caps.

First off, I don't think the people leaving negative reviews about these popping off and not fitting correctly are actually using them how you're meant to. Hence the attachment of photos - they go into the teat screw ring, instead of a teat until such a time that you put a teat on.My baby is combi fed (expressed milk and formula) and when she has formula, she has to have comfort milk which is a bit thicker and can get stuck round the teat when shaking so these are also good for putting on youe bottles while shaking when mixing formula if you have a similar problem to this. Otherwise they are used on bottles storing breast milk in the fridge.There's nothing bad to say at all, they're perfect for what they need to do.

Purchased these to help mixing formula when using the Tommee Tippee perfect prep machine.If you're in the same predicament as I was, trying to find a similar solution to the Tommee Tippee bottle lids then look no further.... Than this review.These are for storing milk only. They click into the screw top where the teat is normally pushed through.Seriously do not buy these, they are unnecessary and useless.In order for these to be used, you have to remove the sterilised teat, shake/mix the bottle, then somehow refit the teat without touching it.Mam bottles are far easier to use, clean and sterilise than Tommee Tippee. These discs take away from those positives.Perfect prep users - just swig the bottle slightly after the hot shot to break up the lumps. Add the rest of the water then shake with the teat and lid on. It works.

Perfect fit, no leaks once they are popped into the ring. I use these for mixing formula and for the day bag when out and about. I place the teat on top of these discs and then put the cap on but you can’t seal the bottle with both on. These also fit Lansinoh Momma bottles but don’t seal well with Lansinoh rings (which are terrible anyway). I don’t think you can write on these ones like you can the rubber ones as these are plastic.

Perfect lids for when your out and about to stop any leaks etc from mam bottles (best bottles available)
