I have been using this brand since my daughter was 6 months old and have had no problems with any of the slow, medium, or fast flow nipples. I do hand wash so I think they last longer than if washed in a dishwasher. I have never had them crack or break. they do kinda change color when I used Similac powder formula, not cows milk though.

These nipples have been good for our primarily breast fed baby, but they do leak a lot, so you have to be careful and watch consumption.

Excellent purchase. My son only uses this bottle system. Very soft and the opening is large enough. Will buy again

They worked great when my son was 6 mo & 7 mo.But, not after that – it was taking him too long to get through his milk after that… more than 20-25 minutes to finish 5 ounces! Bedtime especially had become a really long ordeal. I switched toPhilips AVENT BPA Free Natural Fast Flow Nipples, 2-Packafter that – its so much faster now!

This ended up being too fast for my little one. I was going to return the item, but the seller offered me a partial refund and told me to keep the product. I may end up using it again when he gets older.

My son decided somewhere around 2 that he doesn’t like these wide bottles and he only likes the regular bottle. But when we travelled abroad when he was 9 months, these extra nipples and disposable pouches were a life saver with ever 3-4 hour feeding. Having enough to stay out all day without thinking about cleaning in a foreign country saved my wife and my sanity.

We’ve been using these with our VentAire Plus bottles since it’s so hard to find Fast and Medium flow nipples for those bottles. So if you’re running a Playtex wide mouth bottle you can’t go wrong with these.

These seem to do a fine job for fast flow nipples but I prefer the Tri-cut nipples so that the child can control the flow and there aren’t any drips from the nipple when it’s tipped.

We tried just about every bottle brand out there and, to make a long story short, the Drop ins system stopped our babys colic in its tracks. Love these bottles and the nipples have some type of texture in them that my baby loves and latches easily on to. No leaking or issues whatever.

They should be using these bottles and nipples in the hospitals. These bottles are wonderful. Less gas to baby. Please bring these bottles back to stores and all supplies needed for these.

Hands down, playtex drop-ins are the best and easiest nursing system. No excessive washing necessary, and you can make bottle after bottle. We have traveled for 2 weeks carrying only the one bottle with us. The nipples (slow in infancy) are the slowest flow out there, so there is no nipple confusion if you’re breast feeding. Most lactation consultants recommend these.

my baby chews on her bottle nipples/ avent. but this one, no… i wonder… maybe because it’s very soft. i would recommend to mothers. i bought this because the bottles came with slow drip.

It was taking so long with the slo-flo nipple she was using that now it only takes her about 10 minutes to finish her bottle and she does not get choked from too fast of a flow.

I’m not sure what the reason for the difference is, but I can’t use the regular fast-flow nipples. The leak way too much. The silicone ones … for whatever other advantages they have … also don’t leak.

Flow seems adequate for a 6 month old. Baby seems to like it. It seems to be a good buy.
