Query: Feed With Confidence - A Classic Comes Through For Us

Talk about the toxic chemicals leaching into baby formula from plastic bottles ! To be 100% safe, we chose the old, classic, EvenFlo glass bottles to protect our baby. These arrive with the slowest flow nipple. When baby is older, you can heat up a needle/hat pin to make a second hole, or buy a whole new set of nipples. I get a really good feeling seeing the glass come really clean in the dishwasher. (Plastic just gets more and more cloudy.)Amazon gives you lots of choices on how to purchase glass baby bottles. Before you order, consider the free shipping available on the 3 packs, compared to the cost of shipping on larger packages.
