 Your Lifefactory Baby Bottle is there for the whole adventure, so Lifefactory offers nipples that fit the 4 oz and 9 oz Baby Bottles in four sizes: Stage 1, 0-3 months; Stage 2, 3-6 months; Stage 3, 6+ months; and Y-cut nipples for the fastest flow of milk, formula, or other fluids.

Made of silicone, BPS/BPA/phthalate free, and featuring a vented design, these nipples are made to take everyday adventures in stride.

Our baby bottles are made of the highest quality, thermal shock resistant borosilicate glass. This allows our bottles to transition safely from freezer to boiling water. The silicone sleeves provide a good gripping surface for little hands and help protect against the occasional drop. - Protective medical-grade silicone sleeve provides a tactile non-slip gripping surface and helps prevent breakage - While very durable, our bottles are still glass and are not unbreakable - Dishwasher safe (place cap parts and nipple on top rack/no need to remove silicone sleeve unless desired) - As baby grows we offer a range of caps (sippy and flat) to extend the life of your bottle - Includes polypropylene (PP#5) cap, ring and stopper.
