Life Factory

1) if you have the collar and nipple from evenflo balance narrow they fit on lifefactory glass bottles. 2) I did try evenflo balance wide on different bottles but I don't remember which collar they fit in. I had a couple different collars/bottles and tried several nipples to find the best for my baby that had oral ties. It was one of the avent or wide Dr browns I think. Pigeon fits perfectly in the standard anti colic avent collar, and that collar fits perfectly on glass avent naturals. Pigeo...

Life Factory narrow mouth glass baby bottles are the best and so durable! They are compatible with Dr. Browns narrow mouth nipples too. My friend started out with Avent glass bottles but one broke within the first few weeks. She switched to Life Factory and they lasted all through 3 kids (with nipples replaced). The glass is durable and the silicone sleeves give added protection. Pic of baby holding his own bottle with supervision at 11 months. https://preview.redd.it/nbodzogbfwkf1.png?width=30...
