  1. Love it!
    This is the only bottle my son would take. The small sized bottle are perfect for your LO to hold! The silicone sleeve prevents the glass bottle from breaking, our bottles have been dropped numerous times and they have no cracks. The silicone sleeve also makes it easier for my LO to hold the bottle. The nipple is the perfect size. With other brands my son would gag on the nipple or the nippier was too short and he couldn’t get enough milk out. It comes with a cover that goes in between the nipple and the bottle which makes it great for travelling and no spills! My son loves his lifefactory bottles! My only concern is when it’s time how am I going to ween him from this bottle.
