Baby Bottle & Nipple Compatability
The following article was originally posted on The Glass Baby Bottle website.
Due to all the uncertainty regarding which nipples work with which bottles, The Glass Baby Bottle decided to try and help clear up all this nipple confusion
Some standard guidelines are to use wide neck nipples on wide neck bottles, and standard or regular nipples with regular neck baby bottles. Also, as a general rule of thumb, if a bottle is vented to help prevent colic it is best to use only the nipple designed for that specific brand of bottle. Vented bottles tend to leak and cause irregular feeding when a non-brand specific nipple is used.
One last note, if you tighten the collar and nipple too tightly onto the neck of the bottle, you are more likely to have the issue of nipple collapse. Keep the collar on just tight enough to prevent the liquid from dripping out. Babies are finicky and often times it takes trying several different bottles and age appropriate nipples before finding the best combination for your little one.
Here is a list of the bottles that we carry and the appropriate nipples that can be used:
Weego (Lifefactory) glass baby bottles have their own brand of nipples, yet are compatible with any standard size nipple. The Weego 4oz bottle is supplied with a Stage 1 nipple (0-3 months) and the Weego 9oz bottle is supplied with a Stage 2 nipple (3-6 months).
Silikids glass bottles do not have their own brand of nipples. Silikids bottles are supplied with a Slow Flow Evenflow silicone nipple. Any standard size nipple will work with the Silikids glass baby bottle.
Born Free bottles have their own brand of silicone nipples. Born Free baby bottles are a vented bottle to help reduce gas and colic. Born Free only tests their nipples with their bottles, and do not guarantee compatibility with any other baby bottle.
Dr. Brown’s baby bottles have their own brand of nipple, and are NOT compatible with other nipple brands. Dr. Brown’s bottles come with a unique anti-colic venting system and the nipples are designed accordingly. Using a Dr. Brown’s nipple on a regular non-vented bottle can cause your baby to have feeding difficulties.
Sweet Pea glass baby bottles do not have their own brand of nipples. Any standard size baby nipple will work with the Sweet Pea bottles. The bottles are supplied with a medium flow nipple (3-6 months).
Smitten Baby glass bottles do not have their own brand of nipples. Any standard size baby nipple will work with the Smitten Baby bottle. The bottles are supplied with a slow flow (0-3 month) silicone nipple.
Green to Grow baby bottles have their own brand of nipples. In addition, the Gerber NUK nipples work both with the regular and wide neck baby bottles. The bottles either regular or wide neck are supplied with the appropriate slow flow 0-3 month silicone nipple.
As for Adiri baby bottles, the nipples are an integrated part of the baby bottle itself. The Adiri bottles come in three different stages, to best suit your baby’s needs.

I just wanted to say I’ve found this super-useful! Thank you so much.
Also, we’ve found that you can replace the nipples on a Podee bottle with a standard narrow-neck bottle nipple. Just make sure it’s slow-flow or it will lose suction.
My spouse and I absolutely love your blog and find almost all of
your post’s to be what precisely I’m
looking for. Would you offer guest writers to write content for you
personally? I wouldn’t mind composing
a post or elaborating on a number of the subjects you write
related to here. Again, awesome website!
