Lifefactory baby bottles are fun. Available in 4— and 9-ounce sizes, they come in colorful silicon sleeves that are dishwasher safe and still allow you to see what’s in the bottle. They offer all the advantages of glass and the silicone sleeves make them safer and easier to handle. Lifefactory bottles also grow with baby: you can replace the nipple with a sippy cap for the toddler years or a flat cap to store snacks on the go. Lifefactory nipples come in three stages as well as a Y-cut for older babies who need a very fast flow.
